The Blue Heron II sculpture of stainless steel features hand ground feathers and color fast hand applied blue heat patina. Limited use outdoors, safe on a lanai or covered space. Keep product under a covered area. No direct exposure to water or sunlight. For best results apply a premium wax, such as car or boat wax to the product. Apply prior to hanging outdoors and reapply every 6-12 months. Do not use waxes that contain cleaners (such as boat "cleaner/wax") as these will damage the surface.
