as far as using ppg clearcoats. ppg recommends that you pretreat the metal with dx520 cleaner followed by dx579 metal conditioner followed by clearcoat itself. but, warned, that using this recommended procedure WOULD result in a yellow tint. im trying to figure out a clearcoat to work for the city I live in......Hartsville,s.c. to clearcoat a tin roof for our local waterpark that does hace a lil rust on the tin but, they want to preserve the petina look. this is tough, although I have sold ppg automotive paint products for 30 years.
