Coarse paper mounted with a variety of grit types, used in most stages of surfboard making. For instance, a type of sandpaper known as sanding gauze is often used by the shaper to do a final smoothing and tuning of the shaped blank. Thick-grit paper is used with a disc-sanding machine to cut away excess resin following the hotcoat, and thinner paper grades are used to restore the original shape of the board. Finally, very fine grades of paper are used to cut back the final glosscoat ready for polishing.
