Generally, the car paint is damaged and the primer needs to be touched up. If it's just a scratch, polishing can take care of it. If it is scratched, check whether the scratched part is dented or deformed. If the shape is deformed, plastic surgery is required. The cost of touch-up paint is generally that the 4S shop covers the entire surface. For example, a complete machine cover, a car door, etc. The cost of repainting a surface is generally 300 to 500, depending on the regional charging standards.
