Other than that thread is about painting fenders. Son bought a big tank on the cheap, had beautiful paint .............. that was peeling off . Know nothing about how it was painted. I have seen (read) that tank grafixs for motorcycles are perforated to allow plastic to "breath". Dunno. I think good prep, adhesion promotor, paint, clear might hold up good. Don't know if I would drop $$ on custom paint tho, jmo. I'm actuallly going to try Ritt Dye first, as the tank is natural (off white) , if it doesn't look good enough, I'll paint it. Cain't spoil a rotten egg.
