How do you weatherproof metal garden artwork?

To weatherproof metal garden artwork, start by cleaning the surface thoroughly to remove any dirt or rust. Apply a rust-inhibiting primer to prevent corrosion, followed by a high-quality outdoor paint or sealant specifically designed for metal. For added protection, consider using a clear acrylic or polyurethane sealant to create a waterproof barrier. Regular maintenance, such as touch-ups and cleaning, will help prolong the artwork's lifespan.
