Welcome to Autopia!
Nice car. Very clean combo with the OE kit/rims/spoiler.
Which products are you using to prep the surface? S100, I agree, is very nice on white and yes...white isn't very rewarding. You can get it bright, but the real effect of reflections and wetness is hard to achieve. Jngrbrdman has a white teg in which he has achieved very nice results. Search for his posts.
Oh yeah, are you a member over at Team-Integra.net ?
