This product is a glaze especially formulated by Ranger to adhere to metal. You may use it to seal raw brass to prevent oxidization or mix it with the Vintaj - branded Patinas (which are more like enamel metal paints). This will extend the patina paints and create glaze-like effects. You may also use it as a sealant over other Ranger paints and inks. It will dry to a clear, satiny finish. More instructions are on the back of the package. 2fl ounces.
