In general, polishes are divided into two categories: rough polish and soft polish. This classification of polish is based on the amount of roughness and abrasion power of the polish, and the person who wants to perform the polishing must pay attention to which polish should be used.

Soft polishes are divided into different types, but in general, the use of soft polishes can be summarized in removing surface scratches, and creation of gloss and transparency in the color of the surface.
