There are three main functions of the prototype polishing process:

     1.For the substrate, it is used to remove burrs, oil stains and dust on the surface of the substrate.

     2.For scraping the putty surface, the general surface is rough, need to get a more flat surface through sand grinding, so grinding can reduce the prototype surface roughness.

     3.To enhance the adhesion of the coating. It is generally necessary to polish the old film layer after drying before spraying new paint film, Because the coating has poor adhesion on the excessively smooth surface, the mechanical adhesion of the coating can be enhanced after polishing.
