Use this BlueFire H875P coarse grit paper PSA disc for stock removal, sanding, stripping, and body filler. This disc's next-generation, self-sharpening zirconia alumina abrasive provides a disc life two to three times that of aluminum oxide discs. Its open coat minimizes loading, and its pressure sensitive adhesive facilitates application and removal, while individual discs make for easy storage. The strong E-weight latex-paper backing of this disc resists tearing while remaining flexible, making it an excellent choice for blending body filler, composites, soft materials, and fiberglass.
