Zero Rust® Primer – Gallons

Zero Rust® Primer – Industrial-Strength Gallon Rust Primer for Steel & Metal (1-Gallon Cans – 1, 2, or 4 Packs)

Zero Rust® Primer in 1-gallon cans delivers powerful corrosion protection for large-scale metal restoration and fabrication projects. This high-solids, phenolic-modified alkyd coating creates a long-lasting, oxygen-blocking seal that halts rust development directly on steel surfaces—no sandblasting required.

Perfect for professional and industrial users, Zero Rust® is engineered for application over new, weathered, or partially rusted metal. It offers strong adhesion even on minimally prepared surfaces, saving time and labor while delivering exceptional performance.

This single-component, air-dry primer is easy to apply by brush, roller, or spray and contains no lead or isocyanates, making it a safer, user-friendly alternative to traditional rust primers. Backed by over 2,000 hours of ASTM B117 salt spray testing, it offers industry-proven durability in tough environments.
