Urethane clearcoats provide a degree of protection for the finish that many single stage paint systems do not. As a result it may be possible to correct a number of minor paint defects without refinishing the affected panel. Examples of the types of defects which can be repaired in this manner are shown in the illustration.

It must be noted, however, that in cases where a significant amount of clearcoat has been removed it may be worthwhile to spray an additional coat to ensure long-term durability of the finish. In either case little time is wasted in the process since it is a good practice to clean the repair area with a compound prior to a spot repair.

1. Thoroughly wash the repair area with a mild detergent and water solution.
2. Apply a small amount of fine machine-rubbing compound to repair area and spread evenly with a compound pad.
3. With the polisher running at approximately 2700 rpm, add compound to the repair area. Keep the pad flat against the panel while applying light pressure. Feature lines and panel edges should be hand-rubbed to avoid burn-through. Check the repair area frequently and, if necessary, add more compound.
4. If sanding is required, proceed to step 6. If no sanding is required, apply polish to the repair area and evenly spread with a polishing pad.
5. Keep the pad flat to the panel and allow the weight of polisher to do the work. Use polish sparingly to achieve original shine. Machine or hand polish the repair area first, then blend in with the rest of the panel.
6. Attach a piece of micro-fine sandpaper to a sanding pad. The addition of a small amount of liquid detergent to the water will improve wet-out and sanding performance.
7. Keep repair area wet while sanding. Sand lightly and evenly in 1 direction only, using straight strokes.
8. Using a clean cloth, wipe the repair area clean of water and clearcoat residue.
9. Add compound and polish, as necessary. Often, hand compounding and polishing of a small repair area is all that is necessary to restore the appearance.
