Yeah I agree.. I am usining plain ol Rustoleum Flat black primer... But the last batch of cars I painted had some weird spotting and took almost 24 hrs for the spots to go away... Then it did look glossier than other ones I did.. If you notice one side is more Satin than the other.. .:freak:I agree with Steve it's more satiny than flat, very cool none the less!!!!:thumbsup:
