Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away.Bare metal will corrode quickly andmay develop into a major repair expense. Minor chipsand scratches can be repaired with touch-up materials available from your dealer or other service outlets. Larger areasof finish damagecan be corrected inyour dealer's body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control collect on can the underbody.If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such fuel lines, frame, floor pan, and as exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where and other debris can mud 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 foryou. do Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces 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 defect in the paintjob causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damagedby this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever comes first. 6-56
