i used duplicolor engine enamel /ford dark blue part #de1606..should be available at any parts store(got mine at wal-mart for $3)it doesn't say gloss or flat on it,just ceramic engine enamel..the cap doesn't look like the paint is real glossy,but it is alot glossier(as glossy as you'd want it) in actuality...also the real color is a little lighter than the cap indicates(the perfect shade of blue imho)shows up well,and doesn't look cheesy..and with it being engine enamel it should hold up awhile...send me a pm w/ your email address and i'll take a pic tommorrow and email it to you...i'm very pleased with the results...by all means don't waste ur money on that $40 caliper paint...
