An idea I've been toying with is painting this part to match the rest of the car. I know there was some discussion of this a while back, but I don't recall if anyone had done it. If you have, or have pics of anyone who has, it'd be much appreciated!

Someone with a gray car painted part of the back bumper. It was one of the car shop specialists that visit this forum, like vivid or rotary extreme.. somebody like that.

Edit:
Here you go.
