Abstract
A system and method for coating a desired portion of the workpiece with a layer of paint comprises an upper reservoir for storing paint. A female shell has at least two sections joined together to generally surround the workpiece with a gap. An energy source applies a first voltage of a first polarity to at least one of the shell, a conductive layer of the shell, or conductive inlet associated with the shell. The energy source provides a ground or a second voltage of a second polarity, which is different in polarity to the first polarity, to the workpiece. A lower reservoir receives excess paint that flows off the workpiece. A foam reduction module receives the excess paint positioned between the workpiece and the lower reservoir.
