J-B Weld8237 PlasticWeld Plastic Repair Epoxy Putty - 2 oz.

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 good. The directions say it dries in 5 minutes (if I remember correctly). Sure, its not as smooth, but definitely not dry. It takes a long time to dry, like several hours to fully set. However, that was an advantage for what I was using it on; it allowed me to wipe the excess off the platic outside of the crack I was filling in. No residue or anything left behind. Just a filled in crack!It doesn't dry as white, its more of a gray. And now a month later, it has a tad bit of a purple hue. Not sure if it did that on its own, or from being outside and exposed to all kinds of stuff. Plan on some paint if you want it to stay white. I should also mention, fresh from the tube it smells kind of like rotten eggs, though. Not strong, but you can definitely smell it.

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.

Bought two packages, and held a bumper cover onto the fender clip anchor point using painters tape. Then I masked the channel left over and packed the seam with JB Weld. After a few hours, I peeled the tape of and carefully trimmed away any JB Weld that was not to my liking.This bumper is NOT going to fall off anymore. If the bumper gets damaged in an accident and has to be removed, I can easily cut a hole over the anchor point and remover the bolt that holds it. Bumper can be removed and replaced if needed.I put a before picture up.

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.

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.

i've fixed more things with it that i ever imaged. a broken stone pestle, a chipped screw hole in a table, and much more

Get the kind you mix. This stuff was useless on plastic tank off power washer. I sanded and cleaned per instructions and still leaked prior to testing. It’s like play doe and will not adhere to crack line. Downtime cost money.
