Stick with duplicolor if you have to use sprayIt's the only spray paint I've had the least amount of headaches with when spraying automotive paint over. I usually use Dupont / SEM products too so who knows maybe someone with PPG could spray over Krylon/Rustoleum without problems. I am unsure as to what it is in those paints that causes a chemical reaction and wrinkle in the finish.
