BYD, anti-gravel car body protection in North District.
Anti-gravel car body protection is a method of protecting the car body from fractures, scratches, toxic reagents and other negative environmental factors. Polyurethane is used as an anti-gravel film. Before applying the film, the parts are degreased and softly polished to remove microscratches and fractures on the varnish layer. Next, an anti-gravel film is attached and leveled.
