I know it's been awhile but I finally painted my bike and it went nowhere near according to plan. After pricing automotive paint and then proper respirators I decided to use bike enamel. Then the bike enamel site didn't have some of the paints I wanted and I didn't want to wait. I ended up using Rustoleum Professional Enamel in rattle cans. Since I was doing a couple of different colors, I sprayed the grey first then the blue then finally the green. When I thought I was done with color, I went to spray non-professional Rustoleum clear enamel and the color immediately started to crack and bubble - the paint guy at Home Depot was wrong, they don't work together. Luckily I saw the bubbling quickly and stopped. I re-sanded those areas and resprayed the color.

Overall, even though it looks nothing like I originally imagined, I'm happy with how it came out. It's still really a 5' paint job but I'm fine with that. If I ever build another frame, I'll put more effort into the paint.
