The Twilight in Paris Vintaj® Patina™ kit includes three colors of opaque, permanent, fast-drying inks to make the evening (or anytime) special! Formulated by Ranger Inks, these colors adhere to metal for a romantic patina effect. This kit includes Cobalt (blue), Onyx (black), and Chalcedony (gray). 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.
