Most common causes of corrosion
The most common causes of corrosion
are:
The accumulation of moisture retaining
dirt and debris in body panel sections,
cavities, and other areas.
Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelerated on the vehic ...
