Plastic Weld has a 20-25 minute work life; functional cure occurs in 2-3 hours. Plastic Weld cures to an off-white color, is rated at a tensile strength of 350 PSI. Does not adhere to polyethylene, polypropylene or some other plastics. Test for adhesion first.Use on: Automotive,Ceramic,Fiberglass,Plastic/Composite/PVC and more

Had great success with all JB Weld products. This one was no exception.

I bought a Subaru with a crack in the side mirror. I used my JB weld and it worked great. I will spray paint black to match the mirror when it warms up. Worked Great.

Most likely this is a great product for very small to small repairs only.

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.

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.

I used it to fix a broken plastic wheel socket on clothes dryer. My first attempt failed.Then I sanded the area a bit. And used all the weld instead of a little bit. Left it for 3 days to cure.It worked.

Used it on plastic bumper on car, easy to use, kind of runny but manageable, holding well so far, hoping it holds up thru the cold weather.

I bought this as have a hole in a PVC door, its a new build home and it had a hole in it. The hole was about half the size of a thumb. I eventually found this product and decided to use it. It works like wonders.My only problem or the only issue was I should have taken a little more time to sculpt it into the door. It looks fine, I can see where the hole is, most people would not but if I took my time and sculpted it just a little longer, I think no one, not even myself would have know there was ever a hole in the door.I can only see it ever so slightly but thats just the perfectionist coming out, still looks way better and even from a mater or half a meter from the door, I cannot see the hole. I did not even need to paint it. I simply sand papered it down after using it and it has blended very well.Good product.

Worked well on a dashboard piece, also the bulkines of the product compared to the liquid is great for filling in missing clips, etc. Keep in mind it's not as strong as the liquid version, but still is strong enough of the area has enough surface area

This the strongest epoxy I have ever found of all the different brands. It doesn't care what kind of plastic you are fixing and it will stay fixed. I have repaired my old and over-used home knitting machine when a dozen spacing fins between the knitting needles broke off, rebuilt up the needle bed where is was wearing down, and rebuilt the spindle on the tension dial with it because I couldn't buy the part. It's as good as new as the repairs are holding perfectly. I also used it recently on two broken oil heater dials and the heat doesn't effect the bond at all. I've even made faux decals and dial knobs for my old cars and too many other successful fixes to mention. This is the best and strongest of the epoxy products on the market. I use it exclusively for all my plastic repairs. I can't say enough about how good this product is. It's great! I would give 6 stars if I could.

Got this product to fix the shelves in my fridge door. Had to remold the part of the fridge door that the shelf that sits on. It has been a few weeks so far and it’s worked like a charm. Very happy with this product and would definitely recommend if you need to repair anything plastic

Si pega muy bien, solo es difícil para unir 2 superficies planas. Y deja color blanco al final.Usé el 90% del producto para reparar una maleta grande que se rompieron en el aeropuerto, pude pegar el plástico de arriba de la rueda, ya viaje con la maleta nuevamente y soportó los maltratos del aeropuerto ahora si puedo decir que aguanta bien y soldar nuevamente el plástico
