well i dont know...all I know is that I am PISSED!!! I spent about 5 hours on them already and they are fucked up....o well I guess you live and learn. The thing that I dont understand is why it did it? I didnt use different paints. And the bottle says to do multiple coats. I will try tomorrow and see what happens again, luckly I know someone whos got a sand blaster and I will blast all of the paint off fairly easy and quick, just a waist of money and time....so bumper paint works good? I might try this next time. I will keep you guys posted...THANKS
