Abstract
An apparatus and method for conformally coating an associated generally planar substrate such as vehicle window glass with a coating material includes first (12), second (22), and third (32) coating guns. The first (12) and second (22) coating guns are aimed at opposite sides (42; 44) of the planar substrate and can simultaneously spray a coating thereon. The third coating gun (32) is aimed toward a third side (46), or edge, of the associated substrate. Therefore, the apparatus can simultaneously spray a coating material on target areas on opposite sides and an included edge of a planar substrate such as a vehicle windshield. The third coating gun has an axis which makes an angle .alpha. with a plane containing the substrate to be sprayed. The first and second guns are offset from each other a distance "X", so that overspray from one gun will not foul or coat the other gun.
