Plastic Bumper Filler Tin (16.3 Oz.)

I used this on my '80 Firebird which has very old polyurethane bumpers that rot and sag. Not a lot flex to it and careful with how much hardener you use. It sets very quick and cures well and very sandable and lets paint cure well too. I will use again.

Difficult to work with, but when used correctly is has created superb results. On flexible bumper covers with spider cracks, just sand down with 40 or 80 grit paper then build a layer of this filler. It may need several layers sanding between each layer to get the desired finish. Once it is sanded with the final 400 or 600 grit paper, the bumper looks new again and resists further cracking. Also great for fiberglass panels such as a Corvette so that the stress points flex and don't crack. A flex additive to the final paint is also a good idea.

Great stuff. Only complaint is that there are two packets of hardener (which mixes well with less than one ounce of filler) but this comes with 16.3 ounces of filler). So I'll need to go buy some separate hardener. Little frustration. Otherwise, it worked great on my plastic bumper that had a racket ball size rock go through. I reattached the broken bumper piece with wire mesh and epoxy from behind (took the bumper off).

When I first got this stuff, I thought they did not send along enough activator. As it turns out they sent twice as much as was needed. You only need a very little amount of the hardener and a good mixing with the material. Then it sands well and dries very quickly. This stuff works very well and is somewhat flexible so it is good for areas that may flex some. I would buy it again; in fact I did buy it again. GOOD STUFF!

This stuff works great. I used it to plug a whole in my bumper and looks good as new. It's easy to apply and easy to sand, doesn't crack or peel off.

My daughter backed into a trailer hitch and had a hole in her bumper. We used this to fill the hole and smooth it all out and came out great! We even put a little white paint on it and unless you were looking for it, you would never know there was a hole. Much cheaper than buying a new bumper.

Used it on car bumper. It did work on the two small cracks as they have not enlarged. But it is not working on the back up light fixture. It will not adhere to the bumper.

Bought this product for a golf cart I was restoring that had large gouges in the plastic body panels. Product works easily and sands to a perfect smooth finish. Worked perfect for restoring my Golf cart body before painting.
