Rust-oleum 7779-504 Gloss Black Enamel Coating 1 Qt

Product Description

The RUST-OLEUM 7779-504 is a gloss black oil-based enamel coating formulated to stop rust and protect metal surfaces. It lays down a hard, smooth finish that resists moisture, chipping, and corrosion, making it a reliable protective topcoat for metal components, equipment housings, structural steel, and fabricated parts. The formula is nationally VOC compliant, which satisfies regulatory requirements across most jurisdictions. Trade professionals working in HVAC, plumbing, electrical, and general mechanical service use this coating to refinish brackets, supports, casings, and other metal hardware exposed to weather or corrosive environments.

This coating is suited for residential and light commercial applications where a durable, gloss black finish is required on metal substrates. Common use cases include painting equipment supports, conduit, pipe hangers, service panels, fan guards, and other ferrous metal components. It is applied by brush, roller, or spray to clean, prepared metal surfaces and cures to a hard enamel finish. Sold in quart containers, it is well suited for smaller touch-up and restoration jobs in the field or shop.

Installation Notes

Surface preparation is critical — remove loose rust, dirt, grease, and mill scale before application for maximum adhesion and corrosion resistance. Apply in dry conditions within the temperature range specified on the product label; do not apply to wet or damp surfaces. Adequate ventilation is required during application and drying; follow all local safety and environmental regulations for solvent-based coatings. Allow full cure time before exposing the coated surface to moisture or mechanical contact.
