I have some kind of rough coating on two areas of my car (texture is like sand paper) and as a last resort I started hunting for a clay bar kit. I really wanted the Mother's branded one but the company who sells it via Amazon.com doesn't ship to Hawaii! Checker's didn't have anything..I went to Napa and they had a house brand clay bar kit (80g bar) @ $18.95 - 10% AAA discount.
Anyway, the guy at Napa said that his daughter's car had a similar texture on the paint and the clay bar took it off no problem. Apparently it's from acid rain/industrial fall out. My car was detailed when I bought it so it didn't feel like anything, but since then, it's gotten pretty bad as the wax wears off. I polished my car this weekend so it's hardly noticeable now.
I'm planning on trying the clay bar out this weekend at a friend's house. The roads here in Hawaii are awful so there's also tar not only on my car, but on her grandma's '05 Avalon, so I'll hopefully be able to take that off too.
Any suggestions/tips for a clay bar n00b? Seems like a great product, and people either have no clue what it is, or have heard about it but never used it.
Thanks
PS: There's also light scratches on my car..should I avoid those places with the clay bar or...? No difference?
