Bias-Cut woven sisal fiber is sandwiched between layers of bias-cut cotton and sewed into a packet strip. Intended for those buffing operations that require a more aggressive cutting and leveling action than can be obtained with bias cotton buffs. Type "RS" open-face sisal/cloth buffs effectively remove or blend metal stretcher strains, ripples, score marks, light die and tool marks, and other surface imperfections from drawn, stamped, roll-formed ferrous metals as well as non-ferrous metals. Flexibility is retained, allowing this buff to be particularly adaptable to buffing concave, contoured, recessed and drawn profile forms.
Treatment: Resin dip treatment is recommended when the buffing job requires a stiffer buff with a more aggressive polishing action than untreated buffs can provide. Treating also contributes to longer buff life.
