Is it necessary to repair scratches on the bottom of the bumper?

[VanWeston]

It is not necessary to repair scratches on the bottom of the bumper. The bumper itself is made of plastic, so when it gets scratched, even if the primer is exposed, it will not cause the paint to rust. Toothpaste repair method: When the front bumper is scratched, using toothpaste for repair is very effective because toothpaste itself has a polishing function, which is equivalent to applying a layer of wax to your car, thus achieving a good repair effect. Touch-up paint pen repair method: Using a touch-up paint pen can cover up some small and shallow scratches, making the marks less noticeable. Although there is still a certain gap compared to the original factory paint (color difference), and the durability is certainly not comparable to the original factory paint—after all, the touch-up pen is only for local paint repair—the overall effect is still relatively good.
