- 1). Sand the wheels with 220-grit sandpaper. Sand the entire surface but focus on sanding the pitted areas until they are smooth. Rinse the wheel to see your progress.
- 2). Sand the wheel again using 400-grit sandpaper and water. Keep the sandpaper wet while you are sanding the wheel. Smooth the surface by sanding evenly over the entire wheel. Rinse the wheel to check your progress when you are finished sanding.
- 3). Use 800-grit sandpaper and water to sand the wheel. The 800-grit sandpaper and water makes the aluminum wheel as smooth as a new wheel. Rinse and let the wheel dry completely.
- 4). Spray three coats of clear-coat paint on the aluminum wheels. Hold the spray can 10 inches from the surface and move the can left and right when spraying, not around. Wait 10 minutes between each coat before applying the next.
- 5). Let the wheels dry for a full day before mounting the tires on them or mounting them on your vehicle.
