SAND-LOOP FLEX is a sponge type sanding tool developed with GUNPRIMER’s proprietary Advanced Duraflex Technology. The ultra strong adhesive in the backing holds the abrasive grains strong and tight therefore they don’t come off easily and offers a longer lifespan than any other typical modeling sanding sponges in the market. Available in four types of grits: 200, 400, 600 and 800.
