First, general scratches can be polished with sand wax. The second is scratches. If you can't polish it (you can't see the primer), you can paint it several times with a touch-up pen. Wait until it is completely dried, then try polishing. Third, the primer appears, so it is recommended to deal with it as soon as possible to avoid rusting. The pit can be filled with toothpaste and then covered with a touch-up pen. You can also go to the four s shop and ask them to mix some paint for you to touch (depending on your kung fu). If it is serious, I suggest you apply it! Ask your insurance company, it will not affect the premium for the next year for several times, and then decide whether to insure. Fourth, it is normal to scrape while driving. Find a familiar place to deal with these small problems. Note that painters in many small shops are not skilled enough, and the final result is uneven color and brightness of your car.
