Funny s**t.
Don't Often see that here in Nova Scotia. At first sign the roads are going be icy they dump salt all over them.
That is why you don't see many old cars up here at least not in the winter. Salt eats them alive.
I have my Civic waxed with expensive Acid Rain Paint Sealer and undercoated with $400 Diamond Coat undercoating that is solid and has to be inspected every year. Also run Ice Radial tires like Bridgestone Blizzaks on steel rims.
