SHEETMETAL DAIMAGE If your vehicle is damaged and requires sheetmctal repair or replacement, make sure thebody repair shop applies anti-corrosion material tothe parts repaired or replaced to restore corrosion protection. FINISH D M G E Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare mctal will corrode quickly and may develop intc a major repair expense. Minor chips and scratches be repaired with touch-up materials can available from your dealcr or other service outlets. Larger areas of finish damage canbe corrected in your dealer's body and paint shop. Chemicals used for ice and snow removal and dust control cancollect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean anv areas wherc mud and other debris cancollect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you.
