I am getting my interior pieces painted to match the exterior of the car. My ? is should I buy the billet piece from UPR to accect this or leave the black plastic pieces. I was looking at the window switch kit, ac knobs, headlight knob and white overlay on the ac controls. If you think I should do this should I get the satin finish or the polished version? Thanks for any comments and if you have any better ideas please voice them.
