Abstract: An elongated handle is provided having first and second ends and front and rear opposite longitudinal sides. Brush bristles are supported from and project outwardly from the front side of one of the ends and the other handle end includes a smooth endwise outwardly opening longitudinal bore formed therein. A piston is slidable in the bore and an operator is connected to the piston and rotatable on the other handle end. Rotation of the operator relative to the handle effects longitudinal displacement of the piston in the bore and the handle includes a supply passage therein communicated at one end with the inner end of the bore and opening outwardly through the front side of the handle between adjacent bristles at the other end. The bore equipped end of the handle is of greater cross-sectional area than the bristle equipped end and the front side of the handle includes a delineation zone thereof angulated relative to the longitudinal center axis of the handle between the opposite handle ends.
