1. Wash and Dry the Roof:
- Thoroughly wash the car roof with a car wash soap and sponge to remove any dirt and grime.
- Rinse it with clean water and dry it using a microfiber towel to avoid scratching the paint.
2. Clay Bar Treatment:
- Use a clay bar and clay lubricant to remove surface contaminants such as tar, brake dust, and other particles that may have bonded to the paint.
- Gently glide the clay bar over the roof in small sections, following the manufacturer's instructions.
- Rinse the roof again to remove any clay residue.
3. Sanding (Optional):
- If the paint fading is significant, light sanding may be necessary. Use fine-grit sandpaper (1500-2000 grit) and sand the affected areas with light pressure.
- Be careful not to apply too much pressure or sand too deeply, as it may damage the clear coat.
4. Compound and Polish:
- Apply a rubbing compound using a machine polisher or by hand in a circular motion. This will remove any minor scratches and restore the paint's smoothness.
- Follow up with a polish to refine the finish and enhance the gloss.
5. Apply a Paint Protectant:
- Once the paint is restored, apply a high-quality paint sealant or wax to protect it from future fading and damage.
- Reapply the protectant periodically according to the manufacturer's recommendations.
Remember to work in a well-ventilated area and follow the instructions on the products you use. If the paint fading is severe or you are unsure about any of the steps, it's recommended to consult a professional auto detailing expert.
