My husband was giving a car that has been sitting in his fathers storage for over five years without ever been moved. We are trying to fix it up and sell it but it seems rust has formed on the brake drums/rotors, seizing the car in place. We can't move it at all, it's in a storage unit and we have limited space. Any ideas on how to get rid of the rust, or get the tires to move again, so we can pull it out?????
