1 Sheet Metal Damage If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anticorrosion material to the parts repaired or replaced to restore corrosion protection. I Finish Damage 1 Underbody Maintenance I I Foreign Material Calcium chloride and othersalts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, and other foreign matter can damage your vehicle's finish if they remain on painted surfaces. Use cleaners that are marked safe for painted surfaces to remove foreign matter. Any stone chips, fractures or aeep scratches in the finish should be repaired right away. Bare metal wilI corrode quickly and may develop into a major repair expense. Minor chips and scratches can be repaired with touch-up materials available fromyour dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer's body and paint shop. Chemicals used for ice and snow removal and dust control can collecton the underbody. If these are not removed, accelerated corrosion (rust) can occur on theunderbody parts such as fuel lines, frame, floor pan, and exhaust system even though theyhave corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer or an underbody vehicle washing system can do this for you.
