Probably the most economical way to achieve any kind of surface finish is via a mass finishing system; however, matching an existing finish may require some work. Meaning, you need to select the proper shape media and composition. In most cases, ceramic and plastic media will give you you a slight galvanized pattern appearance. To achieve the 4B type finish, you may have to go to a secondary step process or a dry abrasive organic media.
