Rust Preventive Coating is a high performance coating designed to paint directly on prepped rusted or seasoned metal surfaces to stop rust permanently. Rust Preventive Coating is non-porous and seals and protects many surfaces from water, chemicals, salt, and other corrosive contaminants and is able to be painted over rust. Rust Preventive Coating is an effective anti-corrosive and rust preventive coating that offers superior chemical resistance due to its dense, cross-linked molecular composition and non-porous attributes.
