Simply 50139 J-B Weld PlasticBonder- Black,25 ml

Had a small clip broken off a car boot storage compartment. Was thinking I would need to replace it, as the clip was so small and delicate. I decided to try this JB Weld first, as it seemed a bit of a waste replacing it.Mixes fine, doesn’t smell, and is easy to work with.Cure time seems longer than 15 min to me, but that may be because I had to hold it in place until set.Next morning the repair seems really solid. I applied extra adhesive around the repair for additional strength, as this is not a visible repair.Overall very satisfied.

Great glue, need to reorder

Good quality adhesive for plastics. Worked well where a number of others had failed. A great sting repair that cured in a few hours. Easy to use very versatile and good value. I would recommend.

Why did you choose this product over others?:Half my car bumper was falling off. Had to use it with care because it's black so didn't want my car to get dirty but it worked an absolute treat!Firmly stuck on now, feels very secure. Great product!

It just works. Despite some reviews stating that it is "too wet" and wrongly criticising the incredibly simple cap, this stuff is easy to mix, easy to use (when applying a little common sense) and absolutely tough as old boots.Twist and pull off the cap to open the twin tube dispenser and give the tubes a few taps to make sure there's no air trapped in either, push the plunger to squeeze out the 2 components, ensuring that they come out in equal amounts, mix well and, unless you need a really liquid material, leave for around 5 minutes, possibly even a little longer if you're using it on a vertical surface, so that it thickens up a bit. Do make sure to replace the cap the right way round, though - quite easy to do, since the component liquids are black and white.Once applied, it sets in 20 to 30 minutes (rarely the 15 minutes stated on the packaging), so you will have time to shape and smooth it as it starts to cure and might need to hold, clamp or tape a joint in place for a while. Other than that, once it has fully cured (I ended up leaving it for 24 hours, just to make sure, as it was still soft enough to indent with a fingernail, even after a couple of hours) it is both sandable and any overspill can be cut off or shaped with a sharp blade. I can only guess that those who have said it "didn't set" hadn't taken care to make sure there were equal amounts of the two components before mixing, as it is much like any 2 pack type adhesive or filler - too little hardener/activator means the product won't cure and harden.Honestly, when mixed and applied correctly, this product is so good that I have absolutely no issues with it and have ordered more for various other plastic repairs I need to do!Given how good it is, I think it's pretty good value, too.

Used this to attempt a repair on a cracked car boot trim plastic panel - with mixed results. The product description doesn't say it is only marginally compatible with polypropylene. Also, the stated cure time is way too short - it takes 48h+ at 20C to fully harden.The trim panel had a crack at the corner of an access hole for the rear lamp cluster about 4" long. I applied JB Weld to the interior of the trim panel where it's not visible, to fix both halves of the crack in place.1st attempt: mixed using the supplied wooden spatula and the packaging "mixing tray". No prep on the plastic panel except for degreasing and cleaning. Gooped up the interior of the panel and worked the compound into the crack. Left to set overnight in a warm garage at 20-25c. Next morning, after 16 hours, the remainder in the mixing tray and on the panel was a slightly pliable tacky mass, like sun-baked chewing gum. Also, the bead that I had laid on the trim panel had started to come away from the plastic at the edges.2nd attempt: scraped the half-hardened epoxy off with a razor blade and sanded the area with 120 grit sandpaper and degreased (again). Mixed another batch with a proper spatula and bowl, and gooped the crack again. Left in the sun, with plastic temperature approx 50-55°C for about 4 hours. Noticeably harder after this than the first time. Adhesion appears to be much better, and the edges still adhere to the plastic. Time will tell whether it holds up.

Excellent product. Forms a very firm bond in a short time

Works better than other epoxies I've tried and sets fast. Would buy again.Just make sure you thoroughly mix it with hardener and in equal amounts, the first time I tried it didn't set hard as I didn't mix it equally, second time it set much faster and harder.
