If it's running, why bother with anything more than a cosmetic cleanup that can be accomplished with spray cans of degreaser? You're not going to get anything resembling a show-quality paint job on it without a complete disassembly and a rebuild, so scrape the top layer of crud off and drive! A spit-shine and paint isn't going to accomplish much other than eye candy- - - -just wasted effort in the middle of winter! Concentrate on something more useful than cosmetics, like making sure it starts reliably, runs well, stops, steers, and has a safe lighting system.
