Paint rust: Paint rust is specifically manifested as small rust spots on the surface of the car. For this kind of slight rust, we can use water sandpaper to sand it first, and then apply it with a paint pen.

If the rust is not serious in the large area of small rust spots, you can first gently polish the rust spots with extremely fine water sandpaper dipped in water, wipe it off thoroughly, and then apply a layer of primer to ensure that the rust spots will not expand or aggravate. If it is a new scratch, you can wipe it off and apply primer directly. Generally speaking, the vehicle is equipped with a small can of original paint.

Use ordinary toothpaste to treat it. When you find a new small scar, gently rub the toothpaste and apply a circle to the scratch. Don't forget to apply it again after it rains or after washing the car.This can generally reduce scratches and marks, and can also simply play an isolation role to prevent rust. There is no problem in the short term. Especially the white car paint has the most obvious effect.
