740 Heavy Duty Rust Guard

Chesterton 740 Heavy Duty Rust Guard is a long-lasting, protective coating formulated to prevent rust and corrosion on metal surfaces in aggressive environments. This durable film resists water, salt, and chemicals while remaining breathable, reducing the risk of trapped moisture and extending equipment lifespan.

Ideal for heavy machinery, tools, structural steel, and storage applications, it applies smoothly and dries to a clear, non-staining finish. Its tough barrier makes it suitable for indoor or outdoor use, including marine, industrial, and outdoor storage areas.
