Designed for heavy material removal, the ProSand A259PS coarse grit paper sheet features a premium heat-treated abrasive that cuts faster and lasts longer than standard papers. It’s effective on fiberglass, composites, various metals, and woods. With a latex-saturated, fiber-reinforced backing, this flexible and tear-resistant sandpaper maintains excellent grain retention. Its water-based stearate open coating minimizes clogging and avoids color transfer, making it suitable for both hand and block sanding.
