Is there a difference between external painting and 4S shop painting?
1 Answers
There are differences between external painting and 4S shop painting, as 4S shops have more comprehensive equipment and better paint quality. Below is a detailed introduction to the 4S shop painting process: 1. Cleaning and sanding: After scratches or collisions, sheet metal repair is usually performed first to restore the basic shape. Professional painting and sanding tools are used to remove the original paint, exposing the metal panel. 2. Filling dents: Applying putty ensures a smooth paint surface and fills in any dents. This process is typically repeated three times, as it affects the final painting result. 3. Base preparation: A paint scanner is used to analyze the car's paint, followed by manual fine-tuning. Since different vehicles have varying usage durations, the paint may have slight variations, requiring technicians to compare the paint sample with the car body color on-site. 4. Painting: The main types of paint include standard paint, metallic paint, and pearl paint.
