How To Protect Your Vehicle From Rust Damage
If your car has a metal, rather than plastic, body, it's at risk for rust damage. Some climates and environmental conditions raise the chances of your car rusting even more. For instance, if you live in a particularly humid or rainy location, the moisture can cause the vehicle to rust, especially if the paint has been scratched or nicked.
Also, snow and the salt that cities use to de-ice roadways can also make your car or truck rust over time.
