nortex, I am currently in the process of painting ALL of the interior silver trim pieces in my T4R. I am using three coats of Auto Air colors "aluminum" with an HVLP gun or Iwata airbrush (depending on part size), followed by a two part 2k Urethane which provides an INCREDIBLE gloss coat and almost indestructible protection. Eastwood Paint now makes a really kick ass two part 2k urethane in a spray can which makes this job so much easier! Good luck!
