Vintaj® Green Opal Patina™ is reminiscent of Verdigris on Copper. These opaque, permanent, fast-drying inks are specially formulated by Ranger Inks to adhere to metal and create a patina effect. Simulate distressed and patinated metals, or blend and layer for an endless array of results. Shake vigorously until mixing ball rattles. Apply in small amounts using a paint brush. Use a reliefing block to remove faux patina from raised areas. For added durability, set with a heat tool.
