3MSemi-Rigid Plastic Repair, 34240, 47.3 mL Cartridge, Fast-Curing Urethnane for Automotive Plastic Repair

Great bonding. I had my surfaces prepared I applied the glued. I put the glue gun down clamp the surfaces and it hardened in the tip.

I started the process of fixing up the car I inherited from my parents. The first task was replacing the front bumper cover that was cracked in several places due to my dad hitting the back end of another car. Well, they don't make the cover anymore and I couldn't find one ANYWHERE for sale. So, I took a chance on using this product made by 3M to repair the cover. It was fairly easy to use, but you have got very little time to work with it (literally less than a minute). This stuff WORKED! I am incredibly happy with the end result!

This stuff is amazing!!! I used it to patch a cracked Mini Cooper plastic radiator mounting assembly. Follow the YouTube how to's on best used practices. I had multiple holes to fill, and cracks to fix, and instead of smearing this into intricate crevices, I used it like a wire feed welder to stitch the plastic back together. It works perfectly with a very strong bond. If you're doing multiple repairs at one time, You may need extra mix tips, as the material dries up rather quickly in the mix tip.

Doesn't stick to plastic,metal, or aluminum.

It's a good glue for the harder plastics, but I guess you're getting what you pay for in this case.

Quick drying, pretty good stuff for mending plastic or fabricating a missing piece of mounting plastic

I used this on my 95 BMW 540i front bumper cover to repair some pretty bad damage from racoon hitat about 35-40 mph. Watched some 3M repair videos and used the 3M adhesion promoter with the prep processof sanding, drilling adhesion holes etc. This stuff exceeded my expectations. Plan your work and buy a pack of tips because this stuff dries quick. The repair areas are supporting projector fog lamps, so it had to be strong.I finished up with the ColorRite paint system in Alpine White III. Can't tell anything ever happened.

I used this to repair a urethane bumper on my Corolla. I brought a can of 3M 05907 Polyolefin Adhesion Promoter as stated in the directions to help make this stick to the bumper. I did not want to buy this product and spend all this time doing this work and have it not stick well in the end. I did not have the expensive dispenser gun so I had to improvise with a drill to drill a hole in each epoxy bank and then I used the handle of a screwdriver to push the epoxy out. Make sure that each time you squirt, the epoxy banks are equal because you want to mix it in a 1:1 ratio.All in all, it was wasn't bad to use. I had two issues through:The HARD part (pun intended) was that this glue is so tough that I had to use a metal file to sand the plastic repair epoxy flat! I also had to use a Dremel tool with the grinding stone attachment also and it still took me a long time!The other issue was that I could not use Polyflex (polyester putty) on top of this as stated in the instructions. For those that don't know, polyester putty is like Bondo glazing putty only made for use on flexible plastic parts such as bumpers. Without the putty, I had pinholes and small imperfections. If I had known, I would of picked a different product.Next time, I will use the 3M 05887 EZ Sand Flexible repair instead.
