Gator Premium Multi-Surface Sanding Sheets 120/180 Grit 4 Pack, provide maximum performance and long life. The durable aluminum oxide is bonded to a flexible latex paper making it perfect for hand sanding of irregular surfaces. The 120 grit sheets are best for light stock removal and bare wood sanding, as well as light paint scuffing. The 180 grit sanding sheets are ideal for final surface sanding and preparation before applying paint and stain, as well as light sanding between coats of paint and varnish.
