The RUST-OLEUM 245387 is a high-gloss, direct-to-metal (DTM) alkyd enamel coating formulated for rust prevention and corrosion resistance on bare and previously painted metal surfaces. Part of the V7400 System 340 VOC line, this gallon-size black enamel delivers one-coat coverage with a tack-free dry time of 2 to 4 hours. Its lower-VOC formula (under 340 g/L) is engineered for moderate to slightly severe industrial environments where long-term metal protection is required. Licensed HVAC, plumbing, and general industrial contractors rely on this coating for structural steel, equipment housings, piping, and other ferrous metal substrates.
This coating is suited for both interior and exterior metal applications in industrial, commercial, and institutional settings. It performs well in environments where mild chemical exposure, weathering, and mechanical wear are concerns. The USDA-compliant formula is accepted for incidental food contact use and is suitable for federally registered Canadian food processing facilities, making it appropriate for food-service equipment and related metal structures. Rust-Oleum recommends pairing this enamel with a compatible V7400 System primer to achieve maximum adhesion and corrosion protection.
Designed for use as part of the RUST-OLEUM V7400 System; best results achieved when applied over a V7400 System compatible primer on clean, bare, or previously painted ferrous metal substrates.
Surface preparation is critical before application — remove loose rust, grease, and mill scale using appropriate mechanical or chemical methods. Apply in dry conditions within the temperature and humidity ranges specified on the product label. Use in well-ventilated areas and follow all applicable local VOC regulations and safety standards. Wear appropriate PPE including respirator and solvent-resistant gloves during application and cleanup.
