Vehicle body care requirements vary according to geographic
locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on

trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and underbody
protection.

you to obtain maximum benefit from the corrosion
resistance built into your vehicle.

• Road salt, dirt and moisture accumulation.
• Stone and gravel impact.
