Corrosion protection

Your SUBARU has been designed and built to resist
corrosion. Special materials and protective finishes
have been used on most parts of the vehicle to help
maintain fine appearance, strength, and reliable oper-
ation.

Most common causes of corrosion

The most common causes of corrosion are:
1. The accumulation of moisture retaining dirt and de-
bris in body panel sections, cavities, and other areas.
2. Damage to paint and other protective coatings
caused by gravel and stone chips or minor accidents.
Corrosion is accelerated on the vehicle when:
1. It is exposed to road salt or dust control chemicals,
or used in coastal areas where there is more salt in the
air, or in areas where there is considerable industrial
pollution.
2. It is driven in areas of high humidity, especially
when temperatures range just above freezing.
3. Dampness in certain parts of the vehicle remains
for a long time, even though other parts of the vehicle
may be dry.
4. High temperatures will cause corrosion to parts of
the vehicle which cannot dry quickly due to lack of
Appearance care
