These SurfPrep foam pads are great for sanding and polishing tasks. Cabinet makers who have a hard time sanding or polishing the joint location of molding on a miter door will find these pads very useful. The pads are oversized, with a size of 4' wide and 5.25' long, and are 1/2" thick. They come in a box of 12 and are made of red aluminum oxide. They have a soft flexibility that allows them to ride over profiles without causing damage to the finish. Currently available with 4 holes for vacuum, but SurfPrep is updating to a 6 - hole pattern.
