Designed for aggressive material removal, the ProSand A259PS coarse grit paper sheet features a heat-treated abrasive that cuts faster and lasts longer than typical papers. Perfect for use on fiberglass, composites, metals (including aluminum and titanium), and woods, it’s suited for both sanding blocks and hand-sanding. The latex-saturated, fiber-reinforced backing provides flexibility and tear resistance, while the water-based stearate coating minimizes clogging and color transfer.
