Super-Fine Wet/Dry - Excellent for developing a high level of finish (matte, satin, gloss or high gloss). 2000 Grit is especially good for touch-up repairs on finishes. The wet dry sheets create an exceptionally smooth surface. Can be used dry, or with oil or water. To increase sanding flexibility, soak your sheet in water for 15 minutes prior to use. Keeping your sheets wet will greatly increase the sanding life of your sheets and improve the finish of your work piece. The wet dry sheets come in 5 sheets per pack.
