RE: Gray Primer
My son does auto painting and he has found a spray can primer with alcohol propellant that is compatable with any finish coat. He is getting me some today, I'll let you know what he gives me. I think he said SEM. He warned me about using a spray can primer with other types of propellant as it can make paint from a different system bubble. If you use Duplicolor or Krylon primer use the same brand of paint.
