Steps to wet sanding a scratch:
1. Wash and dry the car. Make sure the area around the scratch is clean and free of dirt and debris.
2. Apply masking tape to the area around the scratch. This will help to protect the paint from being damaged by the sandpaper.
3. Start sanding the scratch with 1,000-grit sandpaper. Use a light touch and sand in the direction of the scratch.
4. Continue sanding the scratch with progressively finer grits of sandpaper (1,500-grit, 2,000-grit, and 3,000-grit). This will help to smooth out the scratch and remove any roughness.
5. Rinse the area with water after each sanding step. This will help to remove any dust and debris that has been created by the sanding process.
6. Apply a rubbing compound to the area. Rub the compound in a circular motion until the scratch is gone.
7. Apply a wax or sealant to the area. This will help to protect the paint from future scratches and damage.
