I've an old pair of Audio note Es that are in a very dark lacquered vinyl wrap (I think), they look their age and the finsh is a bit smeared and cloudy and difficult to get looking clean. Given how cheap I got these and the current cost of buying a recent pair, I'm thinking of having them sprayed by a local body shop who is a friend of a friend.
Is there anything I need to consider in terms of prepping the cabinet to make sure it'd work?
