I vote no. Just put some Mylar. Flipper button wear is so prevalent on this game whenever I see the nuclear side rails I just assume they added them to hide wear.
I have actually never seen a TSPP with a colored powder coat that I liked(the Neon green and pink aren't my taste). I have always wanted to do mine in a light blue though as I feel that would look great. Give it a try and report back here so I can see how it looks on the game. Thanks in advance!
