1957 Plymouth Savoy Resto

Easy way to keep chewing critters out of a car in storage like that. Couple boxes of moth balls. Open one box and leave in interior, trunk, and under the hood. Mice and rats hate that camphor smell. They wont go near it. Cool 57 BTW. Get a universal streetrod harness and wire it up.
Common black pepper sprinkled on the floor of the garage will also work, but sweep it up before starting the car.
