Appearance Care and Protection
from Corrosion
Protection of Body and Paint from
Corrosion
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 cor-
rosive to the metal in your vehicle. Outside
parking, which exposes your vehicle to air-
borne 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.
The following maintenance recommendations
will enable you to obtain maximum benefit from
the corrosion resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or re-
moval of paint and protective coatings from
your vehicle.
The most common causes of corrosion are:
• Road salt, dirt and moisture accumulation.
• Stone and gravel impact.
• Insects, tree sap and tar.
• Salt in the air near sea coast localities.
• Atmospheric fallout/industrial pollutants.
Washing
• Wash your vehicle regularly. Always wash
your vehicle in the shade using MOPAR Car
Wash or a mild car wash soap, and rinse the
panels completely with clear water.
• If insects, tar or other similar deposits have
accumulated on your vehicle, use MOPAR
Super Kleen Bug and Tar Remover or
equivalent to remove.
• Use a high quality cleaner wax, such as
MOPAR Cleaner Wax to remove road film,
