Rust Killer
Technical Data

is a balanced formula of phosphoric acid, wetting agents and extenders. It chemically changes iron oxide (rust) to iron phosphate, forming a tough undercoating which inhibits re-rusting.

Paint can then adhere so closely to the metal preventing moisture and oxygen from attacking the surface, thus resulting in a much longer enduring paint job. It is a rust-inhibiting coating, NOT A PAINT. Surfaces should be top coated after treatment. It is equally effective for both exterior and interior use.

Rust inhibitors are recommended by paint manufacturers. GEM RUST KILLER & METAL PREP meets USDA 1996 guidelines for use in federally inspected meat and poultry plants and current NSF requirements for Registration # 122378, code R2.
