Vintaj® Patina™. These opaque, permanent, fast-drying inks are specially formulated by Ranger Inks to adhere to metal and create a patina effect. Vintaj® Patina™ inks create durable and beautiful effects on metal surfaces. 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.
