Sand Paper

From CosplayWiki

Sand Paper is used in smoothing out foam or for epoxy/paint. Sandpaper runs from "coarse" (40-60), to "super-fine" (360-600). For smoothing out insulation foam, you will probably want a medium sandpaper if you don't have a power sander (80-120), and a fine or very fine sandpaper for dealing with the epoxy (150-240).
