Aging Patinas - a white spirit-based patina for creating patinas that imitate natural tarnishing. To achieve the aged effect, apply a thin layer of patina using a soft, but not fluffy, cloth, brush, or sponge. Best results are achieved when the items are first painted with a primer, e.g., metallic. The patina dries in about two days, and the item can be varnished if necessary. Also useful for aging frames or creating a shabby chic look.
