FINISH D M G E Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Minor chipsand scratches can be repaired with touch-up materials available from your dealer or otherservice outlets. Larger areas of finish damage can be corrected in your dealer's body paint shop. and UNDERBODY2MAINTENANCE Chemicals usedfor 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, floor pan, and exhaust system even though they havecorrosion protection. At least every spring, flushthese materials 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. Yourdealer or anunderbody vehicle washing system do this can for you. CHEMICAL PMNT 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 paint job causes this, Cadillacwill 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. 323
