To fix deep scratches on a car, follow these expert steps:
Step-by-step Process to Repair Deep Car Scratches
- Clean the Area
Thoroughly wash and dry the scratched area to remove dirt, grease, and debris. This prevents contamination during repair
- Sand the Scratch
Use wet sandpaper starting around 800 to 1000 grit to gently sand the scratch and smooth out jagged edges. Progressively use finer grits (up to 2000 grit) to blend the scratch edges with the surrounding paint
- Remove Rust and Prep the Surface
If the scratch has exposed metal and rust, remove rust completely before proceeding. Light sanding also helps prepare the surface for paint
- Apply Touch-Up Paint
Using a fine applicator like a toothpick or a touch-up paint pen, carefully fill the scratch with matching automotive paint. Apply thin layers and let each coat dry thoroughly before applying the next. Avoid putting paint on undamaged areas to prevent noticeable edges
- Apply Clear Coat
After the paint has dried, add a layer of clear coat to protect the repair and restore gloss. Let it dry completely
- Wet Sand and Blend
Wet sand the repaired area again with very fine sandpaper (1500-3000 grit) to level the new paint and clear coat with the original surface. This step smooths out any excess paint and helps blend the repair seamlessly
- Polish and Buff
Use a rubbing compound followed by polish to restore shine and blend the repaired area with the rest of the car’s paintwork. This removes sanding marks and enhances gloss
Additional Tips
- For very deep scratches that go into the primer or metal, filling with paint is essential as polishing alone cannot fix them
- Be patient and allow sufficient drying time between coats and steps to achieve the best finish
- Using quality products like automotive touch-up paint, clear coat, and polishing compounds improves results
This method can significantly improve or nearly eliminate the appearance of deep scratches without needing a full repaint
