Before you attempt to paint your wrought iron gate, understand that metallic surfaces like wrought-iron are subject to rust when exposed to moist conditions. You must coat the wrought-iron gate with a special type of primer, formulated to seal existing rust and prevent future outbreaks. In addition, you should apply a topcoat of a particular type of durable paint, or you will ultimately end up with heavy flaking and peeling.
