Tires To clean your tires, use astiff brush with a tirecleaner. When applying a tire dressing always take care towipe off any overspray or splashfrom painted surfaces. Petroleum-based products may damage the paint finish. 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, floorpan, and exhaust system even though they have corrosion protection. At least every spring, flushthese materials from the underbody with plain water. Clean any areas where mud and other debriscan collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer oran underbody vehicle washing system can do this for you. Sheet Metal Damage If your vehicle is damaged and requires sheetmetal repair or replacement, make sure thebody repair shop applies anti-corrosion material to the parts repaired or replaced to restore corrosion protection. Finish Damage Any stone chips, fractures deep scratches in the finish or should be repaired right away. Bare metal will corrode quickly and may develop into amajor repair expense. Minor chips and scratches canbe repaired with touch-up materials available from your dealer or other service outlets. Larger areas of finish damagecan be corrected in your dealer's body and paint shop. Chemical Paint Spotting Some weather and atmospheric conditionscan 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 etchedinto 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 comes first. 6-45
