Sandpaper grit number 320 is an extra-fine abrasive primarily used for light sanding between coats of finish, preparing surfaces for paint, and achieving a very smooth final finish on wood, metal, and drywall. Primary Uses- • Between Coats of Finish: Sanding lightly between coats of polyurethane, lacquer, varnish, or paint to remove dust nibs, bubbles, and brush marks before applying the next layer. • Paint Preparation: Scuffing up smooth surfaces (like glossy old paint or plastics) so new paint or primer can bond securely. • Wood Finishing: Performing the final sand on bare wood before staining or sealing to ensure an ultra-smooth texture. • Metal and Auto Body Work: Removing light rust, polishing metal surfaces, or feathering out edges on car primer. • Drywall Touch-ups: Smoothing out tiny imperfections in joint compound without gouging the wall.
