Step-by-Step Guide to Repair Car Paint Scratches to the Metal
- Clean the Area: Thoroughly clean the scratched area with soap and water, then dry it completely. This ensures proper adhesion of the primer and paint.
- Sanding the Scratch: Start with a coarser grit sandpaper (e.g., 320-grit) to smooth the edges of the scratch and remove any loose paint or rust. Gradually move to finer grits (e.g., 1500-grit) to create a smooth surface for priming.
- Applying Primer: Apply a thin, even coat of automotive primer to the exposed metal. Allow the primer to dry completely according to the manufacturer’s instructions.
- Applying Touch-Up Paint: Once the primer is dry, carefully apply thin coats of touch-up paint to the scratched area, slightly overlapping onto the surrounding undamaged paint. Allow each coat to dry before applying the next. For black car scratches, learn more about car paint scratch repair black.
- Applying Clear Coat: After the touch-up paint has dried, apply a few thin coats of clear coat, again allowing each coat to dry before applying the next. This protects the paint and provides a glossy finish.
- Wet Sanding and Polishing: Once the clear coat is completely dry, wet sand the area with very fine grit sandpaper (e.g., 2000-grit) to blend the repair with the surrounding paint. Follow up with rubbing compound and then polishing compound to achieve a smooth, glossy finish.
