This clear sealer produces a non-yellowing finish. It can be used as a fixative for pastel, charcoal and pencil drawings, on full-color or hand color prints to prevent bleeding, on wood as a sealer, and as a preservative for maps, photographs and documents. It can also be used over water base and oil base paints, glazes, laquers and varnishes.Plaid Patricia Nimocks Clear Acrylic Sealers - Matte, 12 oz. 1 pack of 1 piece
