I agree that it seems rattle can paint is not that great. I went to a automotive paint shop and got a set, glass jar, screw on throw away canned air. They mixed a pint of black and I used a thinner 4 paint to 1 thinner. IMHO it lays on much better than rattle can, light buff with 600 grit 2nd coat, light 800 grit 3 rd coat 1000 steel wool, tack cloth and commercial canned clear coat.
