Sanding the Filler: Use 80-grit sandpaper to shape the filler to the contour of the car’s body. Progress to finer grits (400, 600) to smooth the surface. Ensure the filler blends seamlessly with the surrounding paint.

What are the best practices for priming and painting the repaired area?

Priming: Apply several light coats of primer to the repaired area, allowing each coat to dry before applying the next. Primer provides a protective base for the paint and enhances adhesion.
Painting: Apply the base coat paint in thin, even coats, allowing each coat to dry before applying the next. Use a spray gun or aerosol can, holding it about 10-12 inches from the surface.
Clear Coating: After the base coat has dried, apply 2K clear coat paint to protect the paint and add a glossy finish. Apply several light coats, allowing each to dry.
Rubbing Compound: Once the clear coat is fully cured (usually after 24-48 hours), use rubbing compound to blend the edges of the repaired area with the surrounding paint. Follow with polishing compound for a smooth, glossy finish.

How to apply 2K clear coat paint and rubbing compound

2K Clear Coat Application: Ensure the base coat is completely dry before applying the 2K clear coat. Apply in a well-ventilated area, using smooth, even strokes. Multiple thin layers are better than one thick layer to avoid runs. Let it dry according to the manufacturer’s instructions, typically 24-48 hours.
Rubbing Compound Application: After the clear coat is fully cured, apply a small amount of rubbing compound to a polishing pad. Use a circular motion to blend the edges of the repaired area with the surrounding paint. This step helps to smooth out any imperfections and create a seamless finish.
