Here are the detailed methods for repairing exposed metal due to paint loss: 1. Paint Pen Repair Method: Using a paint pen with a color similar to the car's paint to apply on the scratched area is the paint pen repair method. However, the adhesion of the repaired paint is not strong enough and can easily peel off. 2. Spray Painting Method: Using traditional touch-up paint methods to repair scratches. The downside is that it causes significant damage to the original paint and takes a long time to complete the repair. 3. Computerized Spray Painting Method: This method combines computerized spray painting with new technology to implement deep scratch repair techniques. It requires accurate color matching and minimizing the repair area as much as possible. After treatment with special solvents, it allows the new and old paint to blend better, achieving optimal adhesion.
