As it was a powder, clean polishing was possible with light force. For planar use, scattering the amount of pachinko ball degree, spraying water gently with misting can polish a considerable area and last long. Because it mixes with water, the resistance to the polisher can be reduced considerably, and I thought that it is easier to use, cheaper and higher performance than honestly other non-silicon liquid compounds. The place of use is oriented to a flat surface to use water. Storage is also good because it is light and convenient to carry and small. There is no need for degreasing after work.
If you are using glasses the surface will scratch and the transparency will drop. It usually scratches when polishing with the 2000 th abrasive, it got scratched rather, the coating was thin and practicality was completely absent, and I tried this 20000 number this time. After carefully watering the cloth and putting the powder on, lightly polishing it improves the transparency and it got scratches to a level where practically no problem.
