How to deal with scratches

A few days ago, someone called and said that the front windshield of the car was scratched, which affected the vision when driving at night. Many people don't want to change the glass, so they find a way to deal with it by themselves, and find fine sandpaper to polish it. Some people think that this can remove the scratches. I would like to remind car owners and friends that this method is not feasible. Not only can the sandpaper sanding method not deal with the original scratches, new scratches will appear during the polishing process, so if there are scratches on the car glass When the injury needs to be repaired, you must find professional personnel to use special scratch treatment equipment. Some chemical materials are used in the equipment to treat the scratches very cleanly without leaving traces.
