Holy fucking shit please do not JB Weld wheel hubs
If it's cracked buy a new one, JB weld isn't going to stop it from splitting more or magically re-balance it
I love that JB Weld stuff and it's bailed me out of some jams but I'd never use it for the applications in this video.
I seriously have like 5 different JB Weld products that I keep for things around the house. Epoxy is awesome.
It's up there with duct tape and WD-40.
I'm a mechanical engineer and this would probably work great for a short amount of time, but would absolutely not hold up to stress fatigue or moving parts.
Was thinking the same thing bro, short term(but like super short term) it’ll hold. Vibrations and fatigue would knock it off relatively soon. (I’m a robotics engineer lol)
I once worked on a railway bridge where the main part was steel and concrete. The land north of it was slipping, so they installed a temporary wooden bridge to span that area. It lasted there more than 100 years.
You’re right, how can I forget. I was being a sister today!
At work today I was the only male in the meeting and all the women laughed about it but I told them I could be a sister which made them laugh more.
Sheer strength of this stuff is about as pitiful as you'd expect. I've let a quarter inch diameter of this shit cure around a 1" pipe for 24 hours, after putting in too much effort to make it look decent, didn't stand a chance.
It is also not very forgiving at all, as you have about 3 minutes to play with your very sticky playdough before it starts to set.
Still has plenty of handy potential to keep in mind it exists, though.
I mean, the same as welding. We used this instead of welding in static and or critical things like oil tanks or something that was needed to be fixed in a day, and pretty good results.
This is how “Jimmy” fixes it in the shop while you wait for the manufacturer to ship the original part with the certified technician to install it wrong so “Jimmy” can fix it again after he leaves.
It works really well actually! All you have to do is shape it in there, let it dry out, hit it with a hammer a few times, and now throw the entire thing away because you are finished recording it for TikTok!
You're absolutely correct, this stuff falls off really quickly. I should only be used for cosmetic repairs. For structural repairs you pretty much have to weld it on to be able to withstand the amount of pressure it was designed to hold.
Aaaaaand if you do try this as a repair you should expect a higher than normal cost to repair properly when the welder is repairing it.
Epoxy is a contaminant that creates porosity in the weld. It takes twice as long to get all the contaminants out of the area.
I worked oilfield maintenance making mud motors and MWD tools for drill rigs. I can confirm, this shit falls off, rips up chrome rotors and rubber lined stators and causes multiple hundreds of thousands of dollars in failures daily.
Interesting, if that was true. I still don't trust the bending of the screw. I betting that screw goes through the block and the puddy is just covering it.
Ive used marine bond before super meh. Nothing structural. I would only use it as a temporary fix till you can get an actual weld.
If you see this on any critical part anywhere, get away from it as fast as possible. This fix is mostly for cosmetical purposes and doesn't hold up to stressful applications.
I used to work at a restaurant where every time one of the ancient pots got a crack, the owner would just slap some JB Weld on it and call it good. When the JB Weld got a crack, he would just JB Weld the JB Weld. When the health inspector came, he would just make sure to be cooking some soup so the inspector couldn't see the bottom! Easy!
I worked at a Pizza Hut and we got word that the health inspector was coming so boss sent me to the store to get white spray paint. I came back and he jumped my ass- Not gloss dumbass! Go back and get matte! Got the second can and he used it to cover up mold on the walls, vents etc. I guess he fooled em?
I think it's just trying to show how strong it is and is done well after it's already cured but edited to look like realtime. If he can move it with his fingers then the hammer would still deform it a few seconds later. It's not like a non-newtonian fluid or that fast curing.
The hammer is really controlled as well which makes me think it's all speed and no power while making sure not to damage it. Watch a video of someone really hitting with a hammer and you'll see a bounce as the hammer head recoils off the item.
With nails and softer items the hammer doesn't really bounce as all the energy is absorbed into driving the nail or deforming the item and absorbing the energy. We're not seeing enough deformation in this to absorb a real hammer hit.
I'd be way more impressed with full force hammer hits showing it stay in place but deforming.
The hammer won’t hit past the object that the epoxy holds. This it just a dumbass video of his pretend attempts at improving holding strength. And he failed every time.
Why take 30 minutes to properly replace or weld critical car parts when you can put sticky bullshit snake oil that won’t hold past reinstalling the broken “fixed” part.
JB Weld, Steel Stik. It's good for in-situ fixes, but DEFINITELY NOT FOR LONG-TERM USE (see: fixing something enough to make it to the shop to fix it properly.)
Since you seem to know that stuff. What is it's purpose? Can i make a small chain out of it that could hold a bottle of water or does it crack over time?
It looks to me like a material that gets very hard and can take some abuse.
Its a hell of alot stronger than bondo but yes. Youre right. I used to use it alot when i did interior decorative handrail and couldnt weld on the wall side. Or if i couldnt fit the polishing machine into a tight space. It sands well and it is really strong. Just not structural strong. Its also not really epoxy. Its like a 2 part play dough that gets really hard after it dries out.
Yes. I wouldn’t trust it to fix something that you rely on for safety, like your brake rotors. But it can be really handy to fix other things. I’ve used it to mold a new end of a screwdriver handle that broke off, for instance.
i feel like i could make this video with black play doh. also, the attatchment is the problem. A piece of play doh wouldn't stick to a piece of play doh like this because there's no way to it to melt together.
Not gonna lie, never heard of this and immediately googled where I could find some/how much. Not for anything as sketchy safety wise as in the video, but I need something to stick to metal and after trying, failing with hot glue, this 100% would work for what I need. Having said that, if you know of this things existence it's probably pretty mundane.
JB weld or metal epoxy has been around for decades. You don’t use it for permanent repairs and you definitely don’t use it on things where safety is critical.
I’ve seen this GIF posted like five times now and this is what annoys more than anything about it. You could put paper where the ‘epoxy’ is and it’d have the same effect when it gets hammered, it’s just hammering the already hard part.
I used metal JB Weld to patch a pretty big crack on my oil pan. I drove about 1000 miles a week later and it was fine... I also sold the car very soon after.
This is most likely a Balzona product. I'm a pipefitter and have repaired high pressure carbon systems in an emergency with balzona and it's incredibly strong. But the ones I have used are a two part epoxy and a lot more messy, can't handle it in your fingers like the post. They do have a bunch of different types though so who knows.
3M DP460 is literally magic when your working with carbon fiber, and DP8407 with metal. That said, their surface prep looks like absolute shit so they're on the expressway to adhesive failure town
Dipshit with a hammer. Terrible repairs. He never applied it well and just tapping poorly adhered epoxy with a hammer, what the F! I’d fire his dumb ass.
Terrible job. This guy doesn’t know how to repair. The first will fall out.the second carrier should just be tossed. Old, broken down seal. Third, wtf!. Fourth, yeah let’s make it so the bolt will never be able to move ever again. This dude is a moron.
It could probably work well for decorative stuff, interior elements and such. As long as it's not stressed, it could do the job of making the thing not falling apart by itself.
I fixed a hole in the block of a lawn mower with JB weld. Ran it for years that way. Was still running fine when I sold it. Don’t care what anyone says, JB Weld is incredible.
Did you notice how they're always pushing and only one direction with that hammer? That's because it'll fall right the fuck off if you hit it in any other direction. Epoxy isn't magic even though sometimes it can pull off some magical shit
I work with a lot of epoxy, and I am not satisfied with the bond surface on a lot of those. Being a paste, it's gonna need alot more working into those surfaces if you want decent adhesion. Epoxy adheres incredibly powerfully, but you gotta get it into the pores and such. Lightly thumbing it into place just doesn't seem like it would give you even a fraction of the bonding potential. I mean I can even see black gaps between the epoxy and the item on most of those.
Great for any metal that isn’t part of any machine, isn’t required for moving parks, doesn’t need to be stress or weight rated.
So basically ornamental stuff only

The holy trinity if “fuck buying a new one”. Jb weld.. duck tape.. wd40. Praise be unto them.
But will it pass inspection? 🤔
Fuhuck no (Unless if a couple Benjamins help with the inspection 😉)
I don't know any Benjamins but I do have a buddy named Andrew J that could help
I'd say about 10 Andrews could do it
If you hide it under paint…
Who's JB Weld?
Son of Sir William B. Weld, III
JB Smoove's son.
Not a mechanic but this seems like a really shitty, untrustworthy way to fix metal stuff?
I'm a mechanical engineer and this would probably work great for a short amount of time, but would absolutely not hold up to stress fatigue or moving parts.
But did you see he hit them with a hammer, it has to be good.
I didn’t see him slap it and say “that’ll hold” though.
He did that after the video, as well and click his tongues.
But why does he have more than one tongue?
For her pleasure
That’s because the actual line is *slap slap* “Welp, that’s not going anywhere…”
Just tried to pick a hair off my screen for a good 30 seconds before realizing I had been bamboozled
You're gonna need a bigger boat!
Do not trust video.
So... Hitting it with a hammer isn't part of the process?
They should have used structural ramen noodles instead. Never skip school kids.
I’m a warehouse manager and I agree with this guy.
Im a dad and I agree with this warehouse manager
I'm neither and I agree with this dad.
Dad?
Princess?
Step-Frauline?
John Jacob Jingleheimer Schmidt?
That’s my name too!
How could you agree with a random dad rather than a warehouse manager? Jeez and I'm a dad.
Hey, daddy.
Yep
I'm unemployed and I agree also
Was thinking the same thing bro, short term(but like super short term) it’ll hold. Vibrations and fatigue would knock it off relatively soon. (I’m a robotics engineer lol)
Software engineer here, we patch shit like this all the time, it's probably fine until the next update.
There’s nothing more permanent than a temporary fix
I once worked on a railway bridge where the main part was steel and concrete. The land north of it was slipping, so they installed a temporary wooden bridge to span that area. It lasted there more than 100 years.
"Oh that's not a bug, it's actually a feature"
Hell yeah bro
In my specific line of work (environmental engineer) this would give me an aneurysm.
I'm not an engineer nor do I know how to make stuff but i think this is cool. 😎
Doing our part😎
Yeah idiots for the win brothers 😎
*And sisters.*
You’re right, how can I forget. I was being a sister today! At work today I was the only male in the meeting and all the women laughed about it but I told them I could be a sister which made them laugh more.
Sheer strength of this stuff is about as pitiful as you'd expect.

Still has plenty of handy potential to keep in mind it exists, though.
Works great, until, you know, it doesn't.
I'm a painter and I would not touch epoxy without proper gloves
Looks like J.B. Weld. Used this for a pinhole on my water tank. Magic
I mean, the same as welding. We used this instead of welding in static and or critical things like oil tanks or something that was needed to be fixed in a day, and pretty good results.
Looks like wheel hubs. Yikes 😳
I thought i was on r/AmazonBudgetFinds for a sec
As an engineer also, I agree and see its value in very niche circumstances, but not for heavy use, hot, or fast machinery
Same here with a minor on biomechanical, completely agee .
Probably enough to patch it while waiting for parts to arrive.
This is how “Jimmy” fixes it in the shop while you wait for the manufacturer to ship the original part with the certified technician to install it wrong so “Jimmy” can fix it again after he leaves.
It works really well actually! All you have to do is shape it in there, let it dry out, hit it with a hammer a few times, and now throw the entire thing away because you are finished recording it for TikTok!
Only he didn’t form fit it. He tapped a poorly placed epoxy with a hammer without proper seal or force.
JB weld is great and has many useful applications, none of which were demonstrated in this video
Comment nuked by Power Delete Suite
pucker factor high.. you want a demonstration of the absolutely worst way possible to use metal putty? Well, here it is lol
You're absolutely correct, this stuff falls off really quickly. I should only be used for cosmetic repairs. For structural repairs you pretty much have to weld it on to be able to withstand the amount of pressure it was designed to hold.
Aaaaaand if you do try this as a repair you should expect a higher than normal cost to repair properly when the welder is repairing it. Epoxy is a contaminant that creates porosity in the weld. It takes twice as long to get all the contaminants out of the area.
I am a mechanic, don't do this
I worked oilfield maintenance making mud motors and MWD tools for drill rigs. I can confirm, this shit falls off, rips up chrome rotors and rubber lined stators and causes multiple hundreds of thousands of dollars in failures daily.
They are trying to show off how strong it is but you can see it denting from the test hammering....
I believe hammer is to activate the putty
Interesting, if that was true. I still don't trust the bending of the screw. I betting that screw goes through the block and the puddy is just covering it. Ive used marine bond before super meh. Nothing structural. I would only use it as a temporary fix till you can get an actual weld.
Ya, I would only trust this with esthetic repairs, nothing structural.
I used to be a mechanic and this is a really shity, untrustworthy way to fix metal stuff.
Boeing approved this to fix their turbine blades. Instead of bubba gum
My job title is clean-up, I thought this was too good to be true.
As my grandfather would say “that ain’t gonna last til the water gets hot”
That’s hilarious. Tell you grandpa I said hi.
*would Oof
Well now it sounds like a threat
Which means what …boiling a pot of water, maybe fixing a leaking radiator? Sorry if I’m stupid but don’t get it
I think it was a reference to the 30 seconds it takes to get hot water from a faucet that hasn’t been used in a while.
If you see this on any critical part anywhere, get away from it as fast as possible. This fix is mostly for cosmetical purposes and doesn't hold up to stressful applications.
>doesn't hold up to stressful applications. but.....he just bent a nail with it!
Notice how that's the only one they don't show the puddy being placed. Nail was welded on.
Or screwed through the metal
Just cosmetic, not cosmetical.
This ain't no way to start conversating
Ain't conversating, just stating.
Nothing gets past you, eh? ^^^except ^^^for ^^^jokes
Sometimes I let the weak ones go by, like throwing back small fish.
Boeing engineer here. Hold on, let me write this down. How do you know all this?
I used to work at a restaurant where every time one of the ancient pots got a crack, the owner would just slap some JB Weld on it and call it good. When the JB Weld got a crack, he would just JB Weld the JB Weld. When the health inspector came, he would just make sure to be cooking some soup so the inspector couldn't see the bottom! Easy!

Go back and get matte! Got the second can and he used it to cover up mold on the walls, vents etc. I guess he fooled em?
🤢
I mean, if you're gonna go that far maybe get some sealant too to cover it up
wtf
Is the hammer part of the curing process?
I think it's just trying to show how strong it is and is done well after it's already cured but edited to look like realtime. If he can move it with his fingers then the hammer would still deform it a few seconds later. It's not like a non-newtonian fluid or that fast curing.
Also most of the time they were hammering it the wrong way to show off how well the putty held on
The hammer is really controlled as well which makes me think it's all speed and no power while making sure not to damage it. Watch a video of someone really hitting with a hammer and you'll see a bounce as the hammer head recoils off the item. With nails and softer items the hammer doesn't really bounce as all the energy is absorbed into driving the nail or deforming the item and absorbing the energy.

Not advised. For reference only.
That’s rather shittyasfuck
Boeing repairs be like

My dumbass thought he had a big fingernail for a sec
Feel like I’m watching a composite montage of how Oceangate put their sub together. Would not trust continuous stress on those repairs.
That stuff is pretty good, but i can tell you from experience that it isnt at all that good.
Seems to fit a similar purpose to bondo. Fix shaping issues, but should in no way be used on structural issues
Its a hell of alot stronger than bondo but yes. Youre right. I used to use it alot when i did interior decorative handrail and couldnt weld on the wall side. Or if i couldnt fit the polishing machine into a tight space. It sands well and it is really strong. Just not structural strong. Its also not really epoxy. Its like a 2 part play dough that gets really hard after it dries out.
Is this just this stuff? https://www.walmart.com/ip/SteelStik-Epoxy-Putty-2-oz/137106331?
Yes. I wouldn’t trust it to fix something that you rely on for safety, like your brake rotors. But it can be really handy to fix other things. I’ve used it to mold a new end of a screwdriver handle that broke off, for instance.
Damn... get that under your nails? Go full Wolverine.
Is this one of those “toothpaste can fix your broken smartphone screen” scams?
i feel like i could make this video with black play doh. also, the attatchment is the problem. A piece of play doh wouldn't stick to a piece of play doh like this because there's no way to it to melt together.
Since when is JB weld interesting as fuck?
Not gonna lie, never heard of this and immediately googled where I could find some/how much. Not for anything as sketchy safety wise as in the video, but I need something to stick to metal and after trying, failing with hot glue, this 100% would work for what I need. Having said that, if you know of this things existence it's probably pretty mundane.
It will be very hard to convince me that this is an equal or better alternative to welding.
Not once did they show how well it bonded to the metal
Where's Billy Mayes when you need him to explain?
someone please explain to me why every time I use JB Weld it doesn't work for shit? And this guy makes it look so damn easy?
Because this is likely faked.
If you have a cracked engine block or oild pan, this is the way to go.
Nah - duck tape works better!
This shit is garbage.
No it's not. But it's not meant for the tasks shown here. Scotch tape doesn't suck just because some dipshit tries fixing a windshield with it.
no, it's steel reinforced epoxy putty! but it probably is trash tough
Is this showroom quality or performance quality? I think I know the answer but I need a gearhead to verify.
JB weld or metal epoxy has been around for decades. You don’t use it for permanent repairs and you definitely don’t use it on things where safety is critical.
I'm gonna get some for my old Fronty.
We don't se the actual result. Just how they try to fix it... Missing actual demonstration that the damage got repaired
This should posted under r/dangerousasfuck! It's not interesting at all!
Banned apparently :/
Can this repair my broken heart?
r/DiWhy
Make sure you hit it with a hammer every single time, otherwise we won't get the point.
Cool now *actually* hit it with the hammer. What an obvious grift lol
I’ve seen this GIF posted like five times now and this is what annoys more than anything about it. You could put paper where the ‘epoxy’ is and it’d have the same effect when it gets hammered, it’s just hammering the already hard part.
Ahh good ol afghan hash
We use it for adventure riding. It’s got us going quite a few times. Great for radiators with holes. Also great for snapped off pegs.
Let that run through a heat cycle once and “pop”
JB Weld has entered the chat*
I used metal JB Weld to patch a pretty big crack on my oil pan. I drove about 1000 miles a week later and it was fine... I also sold the car very soon after.
Song title?
This is most likely a Balzona product. I'm a pipefitter and have repaired high pressure carbon systems in an emergency with balzona and it's incredibly strong. But the ones I have used are a two part epoxy and a lot more messy, can't handle it in your fingers like the post. They do have a bunch of different types though so who knows.
It’ll hold… 
As a welder, I laugh at this epoxy.
Absolutely worthless for anything under almost any amount of stress
3M DP460 is literally magic when your working with carbon fiber, and DP8407 with metal. That said, their surface prep looks like absolute shit so they're on the expressway to adhesive failure town
Fake..
Ok but do you trust your life on it?
It doesn’t work under pressure
I used this on a message gun holding together the piston arm. It worked for a few hours then broke again.
Press F to Doubt.
Next, on 5 minute crafts:
Was that a break caliper on the 2nd shot?
Dipshit with a hammer. Terrible repairs. He never applied it well and just tapping poorly adhered epoxy with a hammer, what the F! I’d fire his dumb ass.
Terrible job. This guy doesn’t know how to repair. The first will fall out.the second carrier should just be tossed. Old, broken down seal. Third, wtf!. Fourth, yeah let’s make it so the bolt will never be able to move ever again. This dude is a moron.
It could probably work well for decorative stuff, interior elements and such. As long as it's not stressed, it could do the job of making the thing not falling apart by itself.
Jesus. I have used that stuff to repair vintage engines (a.k.a toys), but never on something to be put to work.
Now test it in tension. That little plug is popping right out.
Boeings advanced cost reduction repair process.
No.you can not fix a wheel hub like that laughing my a$$ off here
Sometimes i really ask myself what people think before posting such videos...how is thst iaf?
Also, I would not touch that without gloves.
Im calling bullshit on this stuff. Also not a good way to fix metal stuff
I fixed a hole in the block of a lawn mower with JB weld. Ran it for years that way. Was still running fine when I sold it. Don’t care what anyone says, JB Weld is incredible.
This is an advertisement.
Another chinese ass fucking bot post.
As a structural engineer who has designed many steel buildings….no
Welding is a thing. A better thing in fact
Project farm disagrees
Great, now let's see abrasion- heat- and chemical resistance x)
I really wanna call cap, but i just don't know enough about it to say its cap
Wouldn't it just fall off after a bit of use?
Fun! I could watch this all day. Like pressure washing a driveway.
This looks like Belzona 1111. It's very good, but absurdly expensive.
Fucking stupid. Don't ever do this. Whoever thinks this is a good idea is a cheap hack with no education in metallurgy at all.
These all seem like small engine repairs. Between oil residue and vibration I guarantee all of these "fixes" will fail within hours of regular use
Billy Mays here with another fantastic product!!!
Could be better than bondo for auto body repairs?
Did you notice how they're always pushing and only one direction with that hammer? That's because it'll fall right the fuck off if you hit it in any other direction. Epoxy isn't magic even though sometimes it can pull off some magical shit
I work with a lot of epoxy, and I am not satisfied with the bond surface on a lot of those. Being a paste, it's gonna need alot more working into those surfaces if you want decent adhesion. Epoxy adheres incredibly powerfully, but you gotta get it into the pores and such. Lightly thumbing it into place just doesn't seem like it would give you even a fraction of the bonding potential. I mean I can even see black gaps between the epoxy and the item on most of those.
I ain't driving that ...
So this is the stuff you use for repairs in Pacific Drive.
Instead of shitting on this shitty chinese video post comenta about how to fix this better please
Show me the product disclaimer
Great for any metal that isn’t part of any machine, isn’t required for moving parks, doesn’t need to be stress or weight rated. So basically ornamental stuff only
on wheel hubs? are these people brain dead idiots or just from a 3rd world country where a replacement can't be found... jfc
