Having the right tools and materials is essential for a professional finish.

Step-by-Step Guide: How to Repair a Deep Scratch

Clean the area: Thoroughly wash and dry the scratched area to remove any dirt or debris.
Sand the scratch: Start with a coarser grit sandpaper (e.g., 1500-grit) to smooth the edges of the scratch and remove any loose paint. Gradually move to finer grits (e.g., 2000-grit, 2500-grit) for a smooth surface.
Apply primer (if necessary): If the scratch has reached the bare metal or primer, apply a thin coat of automotive primer to prevent rust. Let it dry completely.
Apply touch-up paint: Using a fine-tipped brush or a touch-up pen, carefully apply thin coats of touch-up paint to the scratched area, allowing each coat to dry before applying the next. Build up the paint until it’s slightly higher than the surrounding surface.
Apply clear coat: Once the touch-up paint is dry, apply a few thin coats of clear coat, allowing each coat to dry completely. This will protect the paint and provide a glossy finish.
Sand and polish: After the clear coat has cured, wet sand the area with very fine grit sandpaper (e.g., 3000-grit) to level the surface. Then, use rubbing compound and polishing compound to restore the shine and blend the repair seamlessly.
Wax and seal: Finally, apply a coat of wax or sealant to protect the repaired area and the surrounding paint.
