Patented nano-foam process encapsulates the base of the lambswool fibers with microscopic poly-foam particles. Cuts like natural sheepskin but finishes like a foam pad. Aggressively removes 1500 grit scratches, leaving a lustrous finish with no hazing by reducing compounding swirls. Foamed fibers resist caking and matting.Foaming process also creates minute air pockets at the base of the fibers, which improves cushioning and retention of compounds and polishes. Manufacturing process produces a uniform material, resulting in consistent pad performance unlike performance reducing variances that can occur with natural sheepskin pads. Foaming process locks in the lambswool fibers, significantly reducing linting. Distinctive color for easy identification.
