The outline of the Koup grill is black, while the outline of the sedan grill is chrome. I'm curious as to if the grill on the Koup is plastic or still a metal. I have the sedan, but I'm not a fan of chrome at all and am thinking of painting it. I'm just not sure how well the pain would hold on a chrome surface. So yeah, anyone who can clarify for me, it would be appreciated. Any painting tips as well =] thanks.
