J B Weld Structural Adhesive Tapes for Plastic - Advanced Adhesives & Sealants Review

It's easy to make sure you get equal parts A and B epoxy. It's easy to see when they're well mixed. Easily sandable after hardening. Highly recommended.

I use this to try and fix leaks in the plastic (polypropylene?) ice packs that came with my dog bed. I still have some edge leaks, but that could be due to the way the packaging is made. This is the best product I have found to fix a faulty product. I place it in the recessed area of the connector that is weak around the edges. It appears to hold for a while, then the sticky "stub" pops out. I'm hoping for what's left, but for now it's the best I can find.

I bought this to bond PE to other materials. Works great for this purpose. I deducted 1 star for dosing issues, but I was strongly tempted to deduct 2. Associated syringe plungers are supposed to deliver equal amounts of the a and b components, but that often doesn't happen. I ended up wasting very little as nothing came out on either side. It's not that the corresponding nozzle is clogged, as this affects the back pressure in the piston. As if there were huge air bubbles in the components…
