Another endorsement for spraying with ACF 50, an aviation corrosion prevention fluid. Not only spraying on it on chassis, wheels and suspension but dripping it along seams, especially where aluminium meets steels. Of course the ultimate prevention is to avoid salted roads, but I understand for some that's not possible. The salt spreaders are out in Vienna so the mog will stay in the garage until the spring or a week of rain washes the salt away, whichever comes first.
