The Norton ProSand Small Area Sanding Sponge offers controlled hand sanding for wood, metal, paint, plastic and drywall. Its 36-grit extra-coarse abrasive is suited to removing heavy coatings and material before progressing to finer sanding. Measuring 4-1/2 x 2-11/16 x 1 inch, its flexible, tear-resistant foam follows flat areas, curves and contours, while sharp, open-coat aluminum oxide abrasive resists clogging for efficient cutting and extended life. Rinse the sponge clean and reuse it as needed. Includes one sanding sponge.
