Another vote here, so far. I just got mine and tried it on a few spots on my moms black car. One of the mirrors on her car the black paint looked dull, put some on, left it on for about 4 minutes (I know it recommends 15 but I have ADD) and it looks a lot better, and thats not even leaving it on the recommended time, or claybaring either. Can't wait to see what it does for the stang.
