Can't help ya. But im getting really pissed because it seems like every time i detail my car if find a piece of paint gone from a rock or something lol. Ugh! I think I'm going to trade it next year for a brand spanking new one. I've got the itch lol.
One time i was spraying soapy water off at a car wash and the paint started peeling off the hood ! Took it to the dealer and they repainted the hood and only charged me $100 deductible. Thank you Ford !
