Ya, you can paint them just make sure they are grounded as VetteVet suggested. Also, if you want something a little different you can paint the inside of the tins a different color other than the bright teal/aqua color. I did mine in orange when I initially rebuilt them and it gave off an orange glow instead of the original color when the lights were on. I have also seen them in red, green & yellow. Just a different look without costing but a can of paint, and easily reversed.
