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 fuellines, frame, floor pan 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 retailer or an underbody vehicle washing system can dothis for you. Chemical Paint Spotting Some weatherand 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 etched into the paint surface. Although no defect in the paint job causes this, Oldsmobile 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. Collision Repair Your vehicle was built with composite SMC (Sheet Molded Compound) fiberglass body panels and molded RIM (Reaction Injection Molded) front fendersand bumper covers. Thesepanels require different collision repair procedures than metal-paneled vehicles. See your Oldsmobile retailer for information on collision repair. 6-49
