The 3Mâ„¢ Hookitâ„¢ cleaning sanding painter's back-up pad has a 25-hole pattern to maximize dust extraction, prolonging disc life and improving air quality. Use for auto painting jobs such as following contours and sanding close to edges, and for auto body sanding jobs requiring a finer finish (application of color, primer, and clear coat). Flexible 1/2" soft density foam reduces edge cutting and increases conformability.
