I painted the inside of the skin with high-temperature white paint, and the mounting brackets with high-temp gray. I used Duplicolor brand from AutoZone. The lights are so bright by themselves, it's hard to tell if the white-painted bay will add to the light output, but at least it looks good, IMHO.
Here's a picture showing how far back I painted the bay:

I didn't encounter any issues with the painting process, and the Duckworks kit is really slick.
Have fun with it.
