The Insta Finish Softback Sanding Sponge - Fine, Grits 1000-1200 and 1500 features a foam disc that provides an even surface pressure to the abrasive fabric regardless of the form variations of the sanded material. This prevents the abrasive fabric from cutting through the lacquer layer, for example at sharp edges and rounding. The pad starts as 1000 grits then diminishes to 1200 and lastly 1500, no need to change sandpaper.
