If you had repaired as much rusted out rockers and such as I have, you would know. The later galvanized cars fair better, but given time, they rust, too. Now, if you flushed and dried the car each outing, that would help immensely. But, you have to do it by hand, not just drive over some sprinklers you put in the driveway.

Proper winter prearation would be a big benefit as in cavity waxes before the wet.
