I got behind a totally blacked out G35 once. He had the little plastic covers on his. You could barely tell when he hit the brakes. So dangerous.
Sky, it has been done a little over a year. So far it is holding up well. I sprayed it 4 times, 20 minutes in between coats, once from each direction. I never go through a car wash and when I do wash around my emblems I'm very gentle. I wash my car with a micro fiber cloth. I'll post a pic but you can't take off for dirt. It is 12 degrees here. Not good car washing weather.
Also you might want to check into an F-Sport grill. Mine is tinted dark around the edges.
