Polish out fine scratches and smooth high-build finishes with this 3M Pro Grade sanding sponge. The pliable foam body conforms to curves and reaches into corners that flat sandpaper can't, and the four-sided grit lets you keep sanding when one face loads up.

• Grit: 320 extra fine - final smoothing between clear coats, polishing lacquer and shellac, wet-sanding automotive primer
• Sanding surface: 2-1/2" x 4-1/2"
• Premium mineral abrasive on all four sides
• Pliable foam core conforms to curves, contours, and corners
• Clog-resistant coating extends sponge life
• Use wet or dry on wood, paint, drywall, plaster, and metal
• Rinse with water to refresh and reuse
• Will not discolor surfaces

Tip: Wet-sand with light pressure between top coats - the sponge floats abrasive away from the surface and leaves a glass-smooth base for the next coat.
