[quote=Cody M] ...............Road salt will not hurt your cars paint or cause your car to rust unless the temperature is above 32F. [quote]
Not true, salt keeps the water from freezing at 32deg.F. So the water will still be there below that temperature.
Salt also attracts moisture from the air, so even if there is little to no humidity outside the salt is doing its damnedest to eat the car.
You just can't win.
