Plastic Bumper Filler Tin (16.3 Oz.)

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!

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).

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.

I used this to rebuild the plastic door moldings that had chipped and cracked on my project car. Easy to mix, apply and sand. Paint and primer easily adhere to it. It's held up to 95f summer and -2f winter temps so far and still looks perfect. I will use for all my plastic bodywork from now on.

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.

Have used numerous fillers and they have all had failings, mostly being too touchy about mixing proportions and too 'saggy' or runny, but still too grainy to feather out well. This stuff is vastly better than any other I've used. The products on the shelf in local stores - and I've tried them all - is just lousy. They should be ashamed. Buy this instead.

I used it on the back of the mirrors that where beaten up by stones over 10 years or so. It sands well and holds pretty well. I did use adhesion promoter. Be sure to mix well. I suggest using a mixing pattern that goes 90 degrees to each other.
