The RUST-OLEUM 371670 is a 12 oz aerosol spray enamel formulated for rust prevention and durable surface protection. The finish cures to a gloss ink black color and is VOC compliant, making it suitable for use in regions with strict air-quality regulations. This oil-based enamel bonds to metal, wood, concrete, and masonry surfaces, forming a hard coat that resists chipping, fading, and corrosion. It is commonly applied by HVAC technicians, plumbers, electricians, and facility maintenance professionals to protect metal components, conduit, brackets, housings, and equipment enclosures in both indoor and outdoor environments.
This spray enamel is well suited for touch-up and full-coat applications on metal ductwork, pipe supports, electrical enclosures, equipment frames, and structural steel. The aerosol format allows for fast, even coverage without brushing or rolling. The gloss ink black finish provides a clean, professional appearance on exposed components. It is used in residential, light commercial, and industrial settings wherever a corrosion-resistant protective topcoat is required.
Designed for use on metal, wood, concrete, and masonry surfaces as a protective topcoat or rust-preventive finish coat in trade and maintenance applications.
Surface preparation is critical before application — remove loose rust, grease, and debris for best adhesion. Apply in a well-ventilated area and follow all applicable local regulations regarding aerosol solvent use. Shake the can thoroughly before use and maintain the recommended spray distance for even coverage. Allow full cure time before exposing the coated surface to moisture or mechanical contact.
