To give the composite resin a natural enamel-like glossy look, it is recommended to use a small-grain diamond pastes or aluminum oxide pastes. These pastes should be applied with a felt disc or a soft-brushed brush, to not scratch the surface of the composite resin. This method includes tumble-polishing in a receptacle charged with polishing objects, an alcohol solvent, and silicone articles for a period of time and at a rotation speed sufficient to remove surface irregularities and produce the desired finish and/or improve the optical transparency of the silicone articles.
