6. Advanced Techniques for Deeper Scratches

For deep scratches that penetrate multiple layers, advanced techniques may be required to achieve a flawless finish. These techniques involve more specialized tools and a greater level of skill.

6.1. Using Body Filler

When a scratch is deep enough to create a noticeable indentation, body filler can be used to level the surface before painting.

1. Clean the Area: Thoroughly clean the area around the scratch to remove any dirt, grease, or rust.

Wet sanding is a technique that involves using sandpaper with water to achieve an ultra-smooth finish. It is particularly useful for blending touch-up paint with the surrounding paint.

1. Prepare the Surface: Make sure the surface is clean and free of any dirt or debris.
2. Soak the Sandpaper: Soak the sandpaper in water for at least 15 minutes before using it.
