I put the first color paint on the Flat Boy a few days ago, and the second today. I used the same paints as on my Fat Boy and Micro Fat Boy: Rustoleum 2X Spa Blue and Dupli-Color Metal Specks Retro Red. Masking worked out well, just one spot to touch up.
I tried putting a second color on the Mini Max, too, but I’m not happy with the result. Will sand and try again later.
