ok, tried the first 2 coats on a fender piece i had laying around. cleaned it, cut the rustoleum with mineral spirits, 50-50, rolled on, let stand for 15 min, then rolled it again to get off the bubbles...did the blowing on it trick (yea yea yea) let it dry. An hour later, put on second coat. Stopped there. It sat for about 6 hours and it wont rub off or scratch off with finger nail. Tomorrow, will do the first wet sand and 2 more coats. If it works, i am going to do my 68 camaro this way. I also spoke with a friend who says i should use the marine paint he used on his boat. This guy has painted a couple of hundred cars and says "yeah, you can use a roller, there is no overspray and prep is a lot less"....... here are some pics

it has a nice gloss to it, you can see your reflection in the paint. still need to wet sand and then do coats 3-6
