Solution

1. Preparation

Gather materials: headlight restoration kit, microfiber cloths, water, and masking tape.
Ensure the vehicle is parked in a shaded area to avoid direct sunlight during the restoration process.

2. Mask Off Surrounding Areas

Use masking tape to cover the areas around the headlight lenses to protect the paint and trim from any abrasive material or chemicals used during restoration.

3. Clean the Headlight Lenses

Use a microfiber cloth and a mixture of soap and water to thoroughly clean the headlight lenses.
Dry the lenses with a clean microfiber cloth.

4. Apply Restoration Product

Follow the instructions included in the headlight restoration kit:
- If using sandpaper, start with the coarsest grit (usually 800) and wet sand the lens in a circular motion.
- Progressively move to finer grits (1000, 2000) while keeping the surface wet.
- Rinse off the lens after sanding.

5. Polish the Headlight

After sanding, apply the polishing compound included in the kit with a clean microfiber cloth.
Buff the headlights in a circular motion until the lens is clear and shiny.

6. Apply UV Sealant

If provided in the kit, apply a UV sealant to protect the lens from future oxidation.
Allow it to cure per the manufacturer’s instructions.
