900 Wonder is a premium surface conditioner for ferrous metals. It provides a protective coating against rust, is used as a paint primer and is used to remove rust and corrosion. Other applications include use as a stain remover for porcelain, brick, concrete, vinyl, terrazzo and linoleum. Non-ferrous metals such as aluminum, zinc, brass, copper and bronze can also be treated with 900 Wonder to remove oxidation and corrosion. It is also excellent for treating metal prior to cold galvanizing. Protective Coating: When used as a protective coating for metal surfaces, 900 Wonder stops the corrosion process by changing rust to an inactive state. Rust is turned into a dark protective coating, which resists further corrosion. Paint Primer: 900 Wonder provides a superior bonding surface for coatings and paint that permits better adherence to the metal. It reduces the tendency of chipping and peeling. 900 Wonder fights against rusting and bleeding from underneath finished surfaces, eliminating the conditions that reduce paint and coating service life. Rust Remover: 900 Wonder removes rust on tanks, barges, tools and equipment. Frozen bolts and nuts can be cleaned and then broken out by applying 900 Wonder to the affected areas. It also removes rust from chrome, iron and metals.
