Since you mention retrobrite, I guess you are talking about console shells? Not sure the right term for that, but cases is going to make people think of game cases. For consoles a lot of them have texture, so there isn't much way to do those without removing the texture, but say for the smooth style NES, I think the above mentioned 3M kit might work.
