PROTECTING AGAINST CORROSION Most common factors contributing to vehicle corrosion: 1. The accumulation of moisture-retaining dirt and debris in body panel sections, cavities, and other areas. 2. Damage to paint and other protective coatings caused by gravel and stone chips or minor traffic accidents. Temperature A temperature increase will accelerate the rate of corrosion to those parts which are not well ventilated. Air pollution Industrial pollution, the presence of salt in the air in coastal areas, or heavy road salt use will accelerate the corrosion process. Road salt will also accelerate the disintegration of paint surfaces. ¼ NEVER remove dirt, sand or other debris from the passenger compartment by washing with a hose. Remove dirt with a vacuum cleaner or broom. ¼ Never allow water or other liquids to come in contact with electronic components inside the vehicle. Environmental factors influence the rate of corrosion: Moisture The accumulation of sand, dirt and water on the underside of the body will accelerate corrosion. Floor sections which have snow and ice trapped under the floor matting will not dry. Relative humidity Corrosion will be accelerated: ¼ in areas of high relative humidity ¼ especially in areas where the temperatures stay above freezing ¼ where atmospheric pollution exists ¼ where road salt is used To protect your vehicle from corrosion: ¼ Wash and wax your vehicle often to keep the vehicle clean. ¼ Always check for minor damage to the paint and repair it as soon as possible. ¼ Keep drain holes at the bottom of the doors and tailgate open to avoid water accumulation. ¼ Check the underbody. If any sand, dirt or salt is accumulated, wash it off with water as soon as possible. 6-5
