two posts of info i found - so unless your completely washing your car, with nonrecyled fresh water, at least every 10 days, and I mean the ENTIRE car - like in the engine bay, the underside, all the nooks and crannies - YOUR CAR IS CORRODING faster than mine.....nanny nanny boo boo.... 
Salt also promotes galvanic corrosion throughout the car, which has many different metals in it's construction. With aluminum, steel, copper, brass, iron, and other metals throughout, it's a prime location for trapped salts to attack the substrates as well as attack the bonding of surface coatings to the substrate. Stray current from the battery will aggravate the situation, although once pockets of corrosion begin (at a microscopic size), they can generate their own voltages and current flow to accelerate the problem.
A glance under the hood of salt area cars in this country will show everything from the metal surfaces having surface corrosion to parts of the car perforated and falling apart. I've seen a lot of these cars with only a few year's service that are mechanically and functionally failing .... Even in places where you wouldn't ordinarily look, like under the dash or inside the doors, or brake "tone wheels", or brake calipers.
Two normally used chemicals on the highways during winter for ice removal are potassium chloride and sodium chloride. These chemicals are corrosive and cause oxidation on the surfaces of vehicles. Bare metal has nothing to protect it and it will usually rust, as does any unpainted or coated surface on cars. Painted surfaces that do not have a clear coat on them could and will oxidize as well, hence the need for waxing a clean car. Clear coats will eventually get damaged as well but it takes a much longer time.

Oh my goodness. This is breaking news. Thx for this post bha. I'll be sure to never drive any of my cars in the snow again. I cant imagine the damage we've all caused for ourselves thus far. These cars will probably be worth at least $50 less than what they could have been had they been in a garage on blocks every winter. . Maybe $100
