The flat and even surface is very important especially in the finishing with high gloss result. The # 800 until # 2000 sandpaper are available to cutting the finishing film. The sanding for the top coat is also need to be done gradually by using the coarse sandpaper to the finer. To get the high gloss finish the # 1500 or  # 2000 sandpaper are mostly used as final sanding, but for the low gloss the # 800 grade sandpaper is enough. Many peoples prefer to do wet sanding in the rubbing process, even the dry sanding with a good quality sandpaper also can be used for rubbing. In the wet sanding, a liquid is used to reduce the heat arising from the friction between the sandpaper and the finishing film. The material that is designed to help the wet sanding is called rubbing oil, cutting oil or rubbing lubricant. It is a kind of mineral spirit that contain a very little amount of wax.  A soapy water is also good liquid to do wet sanding with good result.

How the powder work  is similar with the other abrasives, but since it has fine size it will leave very fine scratch mark and create high gloss in the finish result. The powder is usually used to polish the surface that is already flat by the cutting process. The stone powder is applied using a scotch brite with rubbing machine to produce a high gloss surface..
