SuperShine® Hoof Polish & Sealer - Black is a fast-drying (under 60 seconds) hoof polish that gives your horse's hooves a mirror-like finish. The quick-drying formula helps prevent dirt and dust from settling. It seals out excess moisture to harden soft hooves. It does not penetrate beyond the surface of the hoof wall, so it will not harm the hoof. This polish will rub off in a week with the horse's normal activities in the stall, paddock, or pasture.
