Actually, I know a few"old timers" that swear by coating the crap out of their cars with wax and leaving it on when they store them. They say it keeps insects as well as "varmits" from even attempting to get into the car and burrow into the seats etc for winter shelter. Im not saying that this works or doesnt work, but seeing that Chevelle coated with wax in the snow is something Ive seen before in person.
