Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer's body and paintshop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect 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 underbody with plain the 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 this for you. do Chemical Paint Spotting Some weather and atmosphericconditions can create a chemical fallout. Airborne pollutants can fall upon and attack paintedsurfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface. Although no defectin the paintjob causes this, GM will repair, atno charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever comes first. 6-56
