The repair methods for deep scratches and fuzzing on plastic parts of the bumper are: 1. Toothpaste: Toothpaste itself has a grinding function, equivalent to applying a layer of wax to the car, providing a good repair effect; 2. Touch-up paint pen: A touch-up paint pen can cover some smaller scratches, making the marks appear less obvious; 3. Car paint scratch repair agent: It has a grinding effect and can quickly repair the damaged part of the car paint. The bumper not only has a decorative function but, more importantly, serves as a safety device that absorbs and mitigates external impacts, protecting the vehicle body and the safety of passengers. Currently, in addition to maintaining their original protective function, front and rear bumpers of cars also pursue harmony and unity with the vehicle's styling and aim for lightweight design.
