the use of different types of sandpaper when buffing direction

Polishing sandpaper sandpaper polishing must be noted that the problem is one of the ways mechanical polishing, therefore, the use of any kind of mechanical polishing polishing process which are very focused on some of the problems in the process, sandpaper, polishing is no  quick change disc exception, then sandpaper polishing in the application process issues that need attention are those who do? Look at the following three normalized within: 1, must stick with a soft bamboo stick, because in the circle on the spherical surface polishing, the use of drinking stick bamboo stick round face can be better co-ordination and spherical curvature. Conversely, hard wood is suitable for flat surface polishing. Trim the ends of the stick with the steel surface can make it fit shape retention, so to avoid wood or bamboo acute angle caused by contact with the surface of steel deep traces. 2, the use of different types of sandpaper when buffing direction should be suitable angle transformation. This  sandpaper can distinguish between before and after polishing with different abrasive stripe shadow effect left. In sandpaper before changing to a different model, preferably with a 100% cotton dampened with alcohol-based cleaning fluids on the polished surface be carefully wipe, since it is often a little sand left on the surface will destroy the entire polishing work goes on . Polishing process is very particular about cleaning the entire surface, a variety of different sandpaper transform, you must pay attention to this point. 3, in the polishing process, often a lot of time in order to avoid abrasions and burns the  ceramic flap disc surface, so the use of # 1200 and # 1500 sandpaper polishing careful when you place grid. Anyway, with each of the different types of sandpaper polishing, to be used in two different directions, for different angles of the polishing. To avoid scratches during polishing and burn phenomenon.
