Plating on plastics is not a easy task , if you have a plastic piece with some kind of conductive surface we can rebuild over that base but we can not start plating from scratch. for example we can Gold plate a chrome plated logo or vise-versa. sometimes the chrome is not shinny (matte finish) like molding on some Cadillac models. We can rebuild and made the chrome shinny. We can also send your plastics out for vacuum metalizing which is a thin layer of Aluminium.
