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 theunderbody parts such as fuel lines, frame, floor pan, and exhaust system even though theyhave corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areaswhere mud and other debris can collect. Dirt packed in closed areas of the frame should beloosened before being flushed. Your dealer or an underbody vehicle washing system can do thisfor you. I Collision Repair I Chemical Paint Spotting Your vehicle was built with composite SMC (Sheet Molded Compound) fiberglass body panels and molded RIM (Reaction InjectionMolded) front fenders andbumper covers. These panels require different collision repair procedures than metal-paneled vehicles. See your Oldsmobile dealer for information on collision repair. Some weather and atmospheric a conditions can create chemical fallout. Airborne pollutants canfall upon and attack painted surfaces on your vehicle. This damage can taketwo forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into thepaint 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 ltm) of purchase, whichever comes first. 21 7
