Is the entire surface scraped off for touch-up painting?

[SawyerLee]

Touch-up painting is a repair behavior chosen based on the vehicle's condition, which may involve either a specific area or the entire surface. Below is more information about touch-up painting: 1. Process: The specific steps for touch-up painting include determining the repair area, assessing the damage level, applying protective measures, base layer treatment, masking and degreasing, applying color paint, applying clear coat, blending the edges, baking, and finally polishing the painted surface. If loss of gloss occurs during polishing, it can be restored using a high-speed polisher with specialized polishing compound. 2. Precautions: The hardness of the paint after touch-up is lower compared to the original factory paint. High water pressure can damage the car's paint surface, so avoid using high-pressure water to wash the car body.
