Since the debut of the Xiaomi SU7, its "mirror-like" paint finish has become a hot topic. The car’s stunning exterior is attributed to the industrial brushes used for surface polishing before the paint is applied. In the automotive coating stage, industrial brushes are used for surface treatment, such as impurity removal and sanding, to ensure an even paint layer, protect the body from corrosion, and enhance the overall aesthetic.
