Krud Kutter Rustex is a rust inhibiting coating which converts rusted metal overnight into a rust retarding, paintable surface. When applied to rusted surfaces, iron oxide (rust) is chemically changed to iron phosphate, an inert hard substance that turns the metal black. This product is used to increase the paint adhesion and durability of the coating.
