This ProSand A259PS fine grit sandpaper features a water-based, non-pigmented stearate coating that resists loading and clogging. Its color-free design prevents color transfer, while the premium heat-treated abrasive delivers faster cutting and longer life than 3X technology. Reinforced with latex saturation and fiber, it’s tear-resistant yet flexible for folding. Ideal for finishing hard and soft steels, metals, titanium, alloys, woods, fiberglass, and composites.
