Abstract
A method for painting a work piece of plastic material. The method includes applying a first coating of an electrically conductive material to the work piece and electrically grounding the first coating. The method also includes electrostatically charging a paint to render the paint conductive for statically attracting the conductive paint toward the grounded first coating of the work piece. The method also includes overlying a mask of a non-conductive material over at least a portion of the first coating of the work piece and electrically insulating the mask. The work piece is then sprayed with the conductive paint to apply a layer of paint on the first coating with the mask preventing the conductive paint from being applied on the portions of the first coating of the work piece that are covered by the mask.
