J-B Weld 8237 PlasticWeld Plastic Repair Epoxy Putty - 2 oz.

Did it's job well, was easy to use and fixed the issues I needed repaired.

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 plastic 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.

Docked a point cuz it was super messy to knead and put on but- worked well to mend my headphones which snapped! Will update if anything happens.

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 failures4) 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.

Great putty for difficult plastics that epoxy won't repair. I wish that more people know about this product.

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 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 as should but super sticky /tacky ....use gloves
