OSCAR, my current control panel came with a material that seems very similar applied to it.
It's some sort of generic CAPCOM overlay material. I assume it came in the GIGAWING kit that was used on my cabinet. Like the stuff you have, it's thicker than contact paper but still workable. The cool thing is that it is a silver grey and has a "diamond plate" print on it (along with CAPCOM printed now and then).
I wish I could find a source for more. In the pic below, the "GigaWing" text is actually etched into the plexiglas. It's not printed on the vinyl overlay.
