Spray away dude. Once upon a time, the hobby was fun, and people built kits and expressed themselves in the the aestetics and sonics of the final product. That fun evaporated as the prices for most of this junk started to run into four, five, and now six, figures and we got.....well old, old, old. Old people like to tell you that fun is no good for you. Heck, just to buy a can of that spray paint you are going to have to go behind a locked cage at the hardware store and show them your liscense like you are some crazed huffer out to undermine the neatly manicured lawns in the orderly society. Don't believe it for a New York minute; it won't change the sound, but it may make you smile.
