I bought a frying pan at a discount store and when I got home noticed that part of the handle was cracked by where it was screwed on. I mixed up this JB weld and put it on the handle and it is solid as a rock and the handle does not move. I’m impressed!!
Psycho Eddie –
Excellent stuff. I got my bike fearing fixed with it works really well.

3.5 stars for potential. The idea of a putty appealed to me instead of using Bondo which is messy and stinky. My garbage men continuously break my expensive yard waste bins. I thought I would give this a go in rebonding them. It was easy to use and it held up for a while but The fact that the bins are being hastily thrown it only lasted about a month. I do think this product would work great for the right project. This just wasn’t one of them. Would try it again on something different in the future for sure.

Great stuff! Used to repair plastic on UTV and my truck, perfect!

I have to admit, I was pretty wary about trying this, which I used to patch a hole in the wall of a Litter Robot globe. I was first introduced to “JB Weld” in the 90s, and back in those days what you ended up with was a bond that looked like metal, but would easily crumble just by applying pressure with your fingers. THIS STUFF, surprisingly, dried much harder and created a very tight, high quality bond with the plastic globe of the Litter Robot. I experienced none of the difficulties with this that I experienced back with JB Weld in the 90s. It was not runny until dry, it stayed in place, dried and bonded like a boss, and it looks pretty good, considering I haven’t yet sanded it. All in all, this product delivered on its promise, my LR3 globe is once again fully functional, and makes me completely satisfied. There is a bit of a smell when the product is fresh from the packaging, but nothing that I could sense once dried. As for the people who have posted saying it doesn’t dry, it doesn’t work, etc… I have to wonder if they followed the instructions and actually worked the product to mix it as the instructions indicate, because for me, drying was NOT an issue. In fact, I would almost have to argue that it dried a little too quickly. Also, wear gloves when using this product. If it gets on your fingers and dries, it’s difficult to clean off. The instructions say to wear gloves, but I’m impatient.

Works OK, hard to find something that works on various plastics. Got spoiled with their metal epoxy, it never failed me. This is not quite the same range of use on plastics.
Jason Augustine –
Great product. Would recommend.
Michael Auger –
It works well, used it to repair a crack in a plastic bathtub. So far it is holding up well and there is no leaks for the repaired are. Make sure you sand and clean the area to be repaired well, this is to ensure proper adhesion. The only bad thing was the smell, it was so strong, even with the exhaust fan running, I had to leave the area a few times to catch my breath. Good product and works like it says.

Great way to fix a cracked gas tank. Never knew there was a weld for plastic. Saved me a lot of time and money not having to replace that plastic tank. Worked well and easy to use. Just rip a piece off mix it in your hand like clay and then patch it up. It has a little smell but that’s expected. You have a little time before it hardens just have your plan of what you are doing ready. Once you feel it get warm time is running out.

Had a very large, multi-day 3d print fail on me. I was able to print the missing portion but needed to bond the two areas together. because of the large area I needed something with decent working time that would hold over a surprisingly small actual contact area. This was exactly what I needed. so pros:
1) allowed me to fill in the infill at the contact area to create more surface area for the bond.
2) easy to work with after i got a method down (I recommend a test round on something if it’s your first time using it before moving onto your project so you get a feel for it)
3) shapeable both during application and after to help smooth out the shame of your failures
4) surprisingly strong. I needed the bond to hold about a kilo of weight, and after some testing that appears to be more than easy for this.
5) probably the longest working time out of the alternatives for what I was trying to do. (i.e. CA glue, plastic cement… etc)
Cons:
1) just a touch less working time then I would have hoped for. it said 25 minutes, but started to get hard to work with around 15 minutes. Again, WAY more than my other options, but it did lead to extra post processing work I would have liked to avoid.
2) it’s a touch harder once cured than the plastic around it, so when sanding it I was tending to take away more of the base material than than the epoxy, but i sort of expected this going into it.
Until I find a better option for this specific use case, this will remain my top choice.
