Nate,
I haven't seen the entire gill painted by you guys yet. I personally find the F10 M5 gill hideous lol, and would love to hide it as much as possible. Have you guys painted the whole thing including the matte plastic center (not the grill)? Or is the matte plastic hard to paint. My car (when it arrives) will be MC blue. Here is a quick rendering. I'd leave the grill portion black.
Thanks,
G
