Any part requiring post processing must be hand sanded to 600 grit before sending for plating. All layer lines and imperfections must be removed otherwise they will show through the plating and may not come out during the finish steps. This is typically a midway step before sending the part to get gold, silver, chrome and other precious metals. If polished copper is requested, it is recommended to lacquer this shortly after plating.
