Claim 0:
1. An anodizing pen for anodizing a metal surface and comprising:
a handheld housing extending along a housing axis between a first and second end, the handheld housing adapted to be supported by a user's fingers at a distal end during use with the first end extending distally from the user's fingers;
a self-contained reservoir holding an anodizing solution;
a metering valve providing multiple nonzero flow settings and positioned between the reservoir and the metering tip;
a metering tip extending from the first end and communicating through the metering valve with the reservoir to receive and release anodizing solution from the metering tip to the metal surface;
an electrical cable received by the handheld housing and providing a conductor in electrical communication with anodizing solution passing through the metering tip;
further including a user operable control controlling the electrical voltage received on the electrical cable and communicated to the anodizing solution;
wherein the user operable control provides signals to a remote power supply determining a voltage of the power supply from among multiple nonzero values and wherein the electrical cable conducts voltage from the power supply to the anodizing pen;
wherein the anodizing solution and the user operable control are adapted to apply an anodic oxide finish to a metal surface varying in color according to operator manipulation of the user operable control; and
wherein the user operable control provides a control operator exposed through a wall of the handheld housing to be operable by a user hand while the user's hand is supporting the handheld housing;
wherein the metering tip is selected from the group consisting of:
(a) a porous brush providing a conduit between the metering valve and independent multiple filaments conducting anodizing solution there between
(b) a porous stylus sharpened to a point and conducting anodizing solution therethrough
(c) a spring-loaded ball adapted to release anodizing solution when pressed against the surface.
