Patent ID: 8557099

Claim:
A method of applying an electrically conductive coating over a first surface of a reflective coating of a solar mirror, wherein the solar mirror comprises a substrate having a first major surface and an opposite second major surface, the reflective coating having a second surface opposite to the first surface, wherein the second surface of the reflective coating is over a major surface of the substrate of the solar mirror, the method comprising: moving a first electrically conductive liquid material over a first area of the first surface of the reflective coating; moving a second electrically conductive liquid material over a second area of the first surface of the reflective coating, wherein one of the liquid materials comprises an electrodepositable coating composition; maintaining the first and the second electrically conductive liquid materials spaced from and out of contact with one another to provide a third area of the first surface between the first and the second areas to establish a current path through the first liquid material, the third area of the conductive surface and through the second liquid material, and moving an electric current through the current path to deposit the protective coating over the area of the first surface of the reflective coating having the electrodepositable coating composition.
