Krud Kutter Rustex 32 Oz. Rust Converter

A rust inhibiting coating which converts rusted metal overnight into a rust retarding, paintable surface. When applied to a rusted surface, the rust is chemically changed to iron phosphate, an inert, hard substance that turns the metal black. This increases the paint adhesion, and durability of the coating. Easy-to-use: Can be applied by brush, roller, mop, or low pressure sprayer. Treats approximately 600 Sq. Ft. per gallon. Environmentally friendly: Biodegradable, water-based formula is compatible with any paint system. Can be used to etch new galvanized metal.
