What is the best finish for ornamental iron?
Wherever you use iron, indoors or out, iron and steel are prone to rust unless they are properly coated, so gauge your coatings appropriately. If used outdoors near a salt air/water environment, a very substantial coating is required with perhaps hot dip galvanizing followed by epoxy primers and urethanes top coats. If the ironwork is indoors (but not by a pool), a wax coating may be sufficient but lacquers and enamels are commonly used to protect the metal for these applications.
