How can I tell when a car's clear coat is too thin to detail with a PC and an abrasive product. I have some Wolfgang Swirl Remover and I plan to use it on my g/f's 00 Neon. The car is exposed to the elements 24/7 and the paint is very dull looking. However, I dont want to kill her clearcoat if it is too thin. Thanks. :xyxthumbs
