How Long Does the Paint from a 4S Shop Fade?

[Tanner]

4S shop paint can generally last for 4-5 years under normal use. Below is a detailed introduction to the 4S shop painting process: 1. Cleaning and Sanding: After a collision or scrape, the metal panel is first restored to its basic shape through body repair. Professional painting and sanding tools are then used to remove the original paint down to the metal panel. 2. Filling Dents: Applying putty ensures the paint surface is smooth and fills in any dents. This step is typically repeated three times, as it directly affects the final painting result. 3. Base Coating: A paint scanner is used to match the car's paint color, followed by manual fine-tuning. Since paint color can vary slightly depending on the vehicle's age, technicians compare paint samples with the car's body color on-site. 4. Painting: The main types of paint used include standard paint, metallic paint, and pearl paint.
