1. A brush adapted for applying a flowable fluid to a workpiece, said brush comprising:

  • a plurality of elongated filaments formed of a synthetic heat-fusible material and disposed so as to define a tuft of said filaments, said filaments being heat-fused together to form at their proximal ends a head section comprising a non-planar heat-fused wall peripherally bounding an opening, and said filaments being freely movable relative to each other at their distal ends opposite said proximal ends; and

    a fluid distribution channel in communication with said head opening and extending longitudinally along said brush from said head section toward said filament distal ends, said channel being peripherally bounded by a substantially flexible membrane and having an aperture defined at an end of said channel opposite said head section so that fluid fed to brush at the head section is flowable through said head section opening, into and along said distribution channel and through said aperture onto said filaments proximate their distal ends for selective application to a workpiece, said flexible channel membrane being formed of the same material of said filaments.
