Abstract: A brush is fabricated by forming a plurality of filaments into a tuft. The proximal ends of the filaments in the tuft are secured together to define a brush head. An elongated, substantially flexible tube having a longitudinally-extending passageway therethrough is inserted into a peripherally-interior portion of the tuft. The filaments which lie immediately adjacent the tube are then secured to the tube periphery along substantially the full length of the tube so as to positionally fix the tube within the filaments tuft and thereby define an integral and substantially flexible fluid distribution channel in the brush for feeding a flowable fluid through the brush from the brush head to the filaments proximate their distal ends for selective application of the fluid to a workpiece.
