The best paints for painting wrought iron are those that are compatible with the primer and are resistant to chemicals and weathering to protect the substrate and the primer, such as baked phenolic and oil-based or alkyd enamel. Good wrought-iron paints should also be suitable for interior and exterior use.
The best paint for wrought iron depends on the type of surface preparation, performance requirements and surface and environmental conditions. Choosing a matching primer is also important, as it protects the metal and provides a sealed, bonded surface on which the paint is to be applied. A primer and paint from the same manufacturer should be used, as most paint manufacturers create a paint system that works together on a metal substrate.
