Rust Remover coats metal objects with a fresh coat of paint and converts existing rust into a protective black polymer barrier by capturing traces of rain and snow. Long lasting and effective: Automotive Rust Preventive Primer forms a thin composite film that adheres to metal for months, restoring the lustre of cars and metal objects and preventing re-rusting. Metal surface protection: Metal Rust Preventive Cleaner protects iron and metal surfaces on car chassis, bins, railings, and chains; restores metal objects to their original primer colour and easily protects items from rusting. Easy to use: apply the rustproof car paint to the cleaned metal surface, the original rust is transformed into a composite film with strong adhesion, effectively removing rust. Use scenarios: - Automotive maintenance such as underbody, chassis, and exposed metal components. - Outdoor metal items like bins, railings, gates, and fences. - Hardware and machinery parts such as chains, bike components, and storage racks.
