1. A method of applying an electrically conductive paint to a substrate located in a paint spray booth with an electrically charged paint applicator located within said paint spray booth from a color changer at ground potential, said method comprising the following steps:

  • delivering electrically conductive paint through a first delivery line from said color changer at ground potential to a paint cannister located outside said paint spray booth having a reciprocable piston and retracting said piston to receive a predetermined volume of electrically conductive paint in said paint cannister;

    then electrically isolating said color changer from said paint cannister and said electrically conductive paint in said paint cannister; and

    then delivering said electrically conductive paint through a second delivery line from said paint cannister located outside said paint spray booth to said electrically charged paint applicator located within said paint spray booth by extending said piston to drive a predetermined volume of electrically conductive paint from said paint cannister to said electrically charged paint applicator, thereby electrically charging said electrically conductive paint and applying said electrically conductive paint to said substrate with said color changer electrically isolated from said paint cannister and said electrically conductive paint.
