i used it for the first time this past weekend on my sisters bf's car after i washed it for him, and i didnt think it could do such a great job. wow. i acidently hit the black trim with my DAP when i was applying either #9 or #7, and it left an assload of white residue. not to mention it was already graying. one application of b2b and it was a deep black again. i love this stuph. i got it at autozone for like, $6 or something. anybody who already doesnt have it, get it.
