Then, fine sandpaper (240) is used to polish it finely. After repairing the old disc, the same treatment method is used. Polish a small amount of polishing powder with diamond oil to loosen the paste, and continue polishing the disc on 80-150 # sandpaper. The disc needs to maintain a certain humidity, and the polishing powder should be evenly covered on the disc until the surface of the disc is black. Polishing can begin.
