yo... dont know what you mean exactly, but here is mine, i got gauge rings and painted them yellow to match my car and put a carbon fiber raised gell background on them. i had indiglos but hated them, so i left them red and have red lights in my pillar pod gauges and they look sweet they all match.
well its plastic you cant sand plastic.. get a VERY VERY light coat of primer, where it beads before it hits.. i mean VERY LIGHT proly take 5 coats just to cover all the black... let dry good between coats and then paint it with whatever... hi temp paint works well on plastics because it beads faster then normal paint, but again use VERY VERY light coats. put a clear coat on if you want but clear and small surface area = runs easy so be careful. if you decide to use gloss paint be VERY carefeul that stuff loves to run. ive done lots o painting.. good luck. peace- trav
