There are some pics on a LR BRZ with the kit painted. What they ended up painting was the sides of the kit that sit against the body. The winglet areas remained black and the front lip remained black too. Let me find the pic on google as I do not remember where exactly it was in the forum.
Edit: Found it! NIKDENG's post. Just scroll down a little.

Needless to say it looks slick!
