Hey guys I have aluminum, psc fenders and steel psc corner armor. I had a place down town powder coat them. And I'm having alot of chips caused by my tires thrown up and the corner armor is rusting. The fenders haven't rusted because they are aluminum but it looks bad. I think the powder coat was to thin. Anyway my jeep is notna payment princess but the rust spots look like crap. What do you guys do to touch it up? Or should I just pull it all off and go over it with rustolium???
