8237 PlasticWeld Plastic Repair Epoxy Putty - 2 oz.

I've used this J-B Weld PlasticWeld epoxy putty a few times around the house, and it holds up pretty nicely. it's handy for repairing my plastic garden tools and small cracks in the kayak. the application is easy, and it dries pretty quickly. glad i have it in my toolbox for quick fixes during projects or while camping 🛠️. definitely a good addition to my repair supplies!

Fantastic product if you know how to use it properly. Cures extremely hard and bonds to plastic well. Its a little messy to use, but it is manageable when using gloves. I used it to fix my car's wind deflector which shattered into several pieces, some of which were missing. After sanding and painting, I tlreally cant tell the difference between the putty and the original parts. Its a bit overpriced for such a small amount, but it did what I needed it to do.

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.

Works great

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.

More of a rubbery feel than hard plastic.

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.

Gotta say, it's held up better than I expected it to. Applied this over my sideview mirror that was loose and wiggling around especially while driving on the highway. It hardened almost overnight, and I noticed the morning after on the way to work that my mirror was no longer rattling nor creating wind noises on the road. Good to note that I did apply it the night of an ice storm, so already it has held through water and weather exposure. It is also rock hard, like a cast. Hopefully this thing keeps its strength intact long run, if something changes I'll try to update this review. For now however, I can say I made a professional mess and somewhat of a fix to my car for only $10. Might be ugly but you won't notice if I'm zooming past you on the road anyways.
