1: If the scratch is not exposed to the primer of the car, but only slightly, then the scratch will disappear with a light rub with sand wax. 10 minutes at most.
2. If the scratch is very shallow, each automobile fitting department has a touch-up pen available, so you can make it up by yourself.
3. If the scratch is deep, the primer has been exposed, or there are deep grooves, it needs to be plastered with putty, polished smoothly, then plastered with red ash, and then sprayed with primer to see the effect, and finally sprayed with paint (computer-mixed paint, no color difference), 1-2 hours can be completed, and the effect is very good, and it is simply impossible to see that it is a repair.
