Does the 4S shop repaint an entire panel or just a small section?
1 Answers
4S shops generally repaint the entire panel, although the front and rear bumpers can be partially repainted depending on the actual situation. Repainting the entire panel helps avoid color discrepancies. 4S shop repainting process: Masking and degreasing; removing old paint and feather edging; applying putty; sanding putty and old coatings; cleaning, degreasing, and masking; spraying intermediate primer; applying indicator layer and sanding intermediate primer; sanding transition areas; cleaning; masking and degreasing. Thoroughly mix the primer using a paint mixing stick or stirring rod; connect the air hose, adjust the spray gun, and check if the spray gun is properly adjusted through a spray pattern test. Spray the intermediate primer according to the product's application instructions; perform three-layer spraying; dry and wet sanding after painting. Precautions after repainting: Check the color difference between the new paint and the original car paint. It's best to inspect the paint surface in sunlight, as color is greatly affected by lighting. Check the smoothness of the paint surface, ensuring there are no pits, impurities, or runs. Pay attention to the baking time for newly painted surfaces. Avoid washing the car or exposing it to chemicals and grease before the paint is fully dry, as these can easily damage the paint. Avoid covering the newly painted surface with a car cover, as it can cause fine scratches. Park the car in sunlight as much as possible to help the paint dry thoroughly.
