How to best repair the scratches on the car body?

Hello, I have encountered this kind of problem. My driving skills are not too hard, and the body is often scratched and looks ugly. It's especially expensive to go to a 4S shop. So I learned to repair and spray paint, and the effect was still very poor. Now share my repair method.

1, hair cut. Just like tiny scratches, they can be removed by grinding or applying abrasives. Basically, scratches like hair can disappear with a light brush.

2. Toothpaste, touch-up pen and scratch repair agent can all be used for repair. Toothpaste has the function of polishing, but toothpaste repair can only be used for minor marks. A touch-up pen can cover up some minor scratches and make the marks look less obvious. Repairing agent has the function of polishing and can quickly repair the damaged parts of car paint.
