Step-by-step scratch removal methods

Removing surface scratches

To remove surface scratches, simply use polishing paste and a microfiber cloth. The polishing paste gently removes the top layer of paint, smoothing out the scratch.

1. Clean the door surface of dirt and dust.

2. Apply a small amount of polishing paste to the microfiber.

3. Polish the scratch in circular motions, applying gentle pressure.

4. Remove excess paste and check the result.

Removing medium-deep scratches

For deeper scratches, use fine-grit sandpaper (e.g. 2000) and polishing paste.

1. Moisten the sandpaper with water.

2. Gently sand the scratch until it becomes less visible.

3. Use polishing paste to restore the shine to the paint.

Removing deep scratches

Deep scratches require the use of a paint touch-up marker or professional repair at a workshop.

1. Clean and dry the damaged area.

2. Apply the marker along the scratch, filling in the paint loss.

3. Once dry, smooth the surface with polishing paste.
