Finish Damage Any stone chips, fractures or deep scratches the finish in should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Chemical Paint Spotting Some weather and atmospheric conditionscan create a chemical fallout. Airborne pollutants can fall upon and attack painted surhces 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 paint job causes this, Buick will repair, at no 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 occurs first. Minor chips and scratches can be repaired with touch-up materials available from your dealer or other service outlets. Larger areasof finish damage can be corrected in your dealer'sbody and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collecton the underbody. If these are not removed, accelerated corrosion (rust) occur on the can underbody parts such as fuel lines, frame, floorpan, and exhaust system even though they have corrosion protection. At least every spring, flush thesematerials 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 car washing system can do this for you. 6-49
