Mine was scratched up a little bit but I decided to just leave it as is and masked over it and had the CP painted. How rough does yours look?
My wife is a photographer and shot this after I picked it up but you can see my graphic on the front.
At my work I design labels and stickers for our machines we make and if I wanted to reproduce that art, I might go with having it printed on vinyl or maybe a clear vinyl. I think the typical polycarbonate most arcade graphics printers use is thicker and might make it look bulky on the front.
