Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Minor chips and scratches can be repaired with touch-up materials avaliable from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer's body and paint shop. Magnesium Wheel Finish Notice: Improper paint repair or refinishing can cause corrosion damage to a magnesium wheel. See your dealer if a magnesium wheel needs paint repair or refinishing. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you. Carbon Fiber Hood (Z06 Commemorative Edition Model Only) The hood on the Z06 Commemorative Edition model is made from an advanced carbon fiber composite. Under certain lighting conditions, the carbon fiber has a faint woven appearance and can be seen through the paint, but not felt. It is most obvious when viewing the reflection of an object in the surface of the hood. The edges of the object in the reflection will appear slightly jagged, due to the woven carbon fiber material. This is normal. No special care is needed. Titanium Exhaust System (Z06 Only) Time and high performance driving conditions can cause a color change in titanium exhaust system parts. This is normal for a titanium surface. 5-89
