LC Purple Foamed Wool Pad
Foamed Wool is a patented process that places a bottom cushion of microscopic polymer foam particles under a top layer of lamb’s wool fibres.
Lake Country Mfg. developed these pads for high production, OEM/Industrial users. Aggressively removes 1500 grit scratches, leaving a lustrous finish with no hazing by reducing compounding swirls while retaining a high gloss Patented process encapsulates the base of the lamb’s wool fibres with microscopic polythene foam particles. Cuts like natural sheepskin but finishes like a foam pad. Foamed fibres resist caking and matting, foaming process also creates minute air pockets at the base of the fibres, which improves cushioning and retention of compounds and polishes.
