I had a dump trunk drop some rocks on me and gouge the plastic in my bumper. I had someone try to touch it up for me, but without extensive work, it looked pretty bad (photo 1#). Using the 040 white base coat, followed by the 070 white pearl, then the 00C clear coat with some sandpaper and polish, I was able to repair the damage myself. Be sure to clean the area well with Dawn soap to remove any wax. Avoid touching the chip with your fingers so you don’t introduce oils to the area. If your plastic is gouged and has raised edges like mine (it looked like teeth marks), use sandpaper to remove any raised spots. Take your time with the base coat and use the brush. The ball point on top of the bottle is useless. Just put down enough so that it’s completely white and that no metal or plastic is showing underneath or at the edges of the chip (photo #2). Once that dries, add the pearl coat. I did a few coats of that, then used 1000 and 1500 grit wet sand paper to work out any raised spots and smoothed it down (photo #3). Then I gave it one last light coat and hit it gently with 2000 grit. Once that dries, I added the clear coat. You can apply the clear coat past the edges of the chip. Once that fully dries, use 1000 grit, then 1500 grit, and finally 2000 grit wet sand paper to smooth it out. Finally, use something like Mother’s polish to bring back the shine (photo #4). Give the paint a few days to cure, then add wax. I can barely tell that I had a pair of 1/2″ gouges next to each other on the edge of my bumper.
