Fixing A Paint Screwup

since you used rattlecan paint. Just get yourself some acetone and wipe off the old paint. It will come right off. Then clean the part with some dish soap and water with a light scuff pad. Wipe part down with some Isopropyl alcohol. Then get some "bulldog" in a spray can which is great stuff BTW (it's about $15 a can). Do a couple light coats of it. Then light coats of your paint. Should turn out great.
