Rust-Oleum 7769402 Professional High Performance Rusty Metal Paint Primer, 1 Gallon

Rust-Oleum 7769402 Professional High Performance Rusty Metal Paint Primer, 1 Gallon

Rust-Oleum 7769402 Professional High Performance Rusty Metal Paint Primer is a brush-on primer built specifically for metal surfaces that are rusted or have been rusted in the past, and it ships in a 1 gallon container sized for larger maintenance and repaint jobs. It's part of the Rust-Oleum Professional High Performance Protective Enamel system, which pairs a dedicated primer with a matching Professional enamel topcoat so the two coats are formulated to work together rather than as unrelated products. The can's label band reads "7769 RUSTY METAL PRIMER," confirming this is the Professional line's designated primer for metal that already shows rust, not a general-purpose metal primer. Contractors, facility painters and maintenance crews use it as the first step before applying a Professional enamel finish coat over previously corroded steel and iron surfaces.

Key Features

• Type: a brush-on rusty metal primer; the can's label band reads "7769 RUSTY METAL PRIMER" to identify it within the Professional lineup.
• Size: 1 gallon container, sized for larger metal priming jobs where a smaller quart or pint would run out quickly.
• Line: part of the Rust-Oleum Professional High Performance Protective Enamel system, built to be used alongside the matching Professional enamel topcoat.
• Use: formulated to prime rusted or previously rusted metal before a Professional enamel topcoat goes on, giving the finish coat a more stable, prepared surface to bond to.
• Application method: applied by brush, which suits detail work, touch-up areas and job sites where spray equipment isn't practical.

Technical Specifications

• Product Type: Paint Primer
• Series: Professional High Performance

Typical Applications

• Priming rusted railings, gates, fencing and other outdoor metal before a Professional enamel topcoat is applied.
• Previously rusted equipment, machinery and tools that are being repainted with a Professional enamel finish.
• Metal tanks, frames, brackets and other structural components that already show surface rust.
• Maintenance and touch-up priming on job sites and in shops where rusted metal needs a stable base coat before finishing.
• Larger metal priming projects where the 1 gallon size covers more surface than a quart or pint would allow.

Why Rust-Oleum?

Rust-Oleum designed this primer as the designated rusty-metal step in its Professional High Performance Protective Enamel system, so it's formulated to pair directly with the matching Professional enamel topcoat rather than stand in as a generic substitute. The 1 gallon size and brush-on format make it practical for contractors and maintenance crews priming larger areas of rusted metal before finishing. Using the matched Professional primer and enamel together keeps the prep step and the finish coat working as one coordinated system rather than mixed products that weren't engineered for each other.
