Stop rust permanently with Heavy Red Oxide Primer RO-350 - the professional phenolic-modified alkyd primer that blocks 99% of damaging UV rays while providing exceptional rust reformation and corrosion control. The foundation of serious anti-corrosion systems.

Heavy Red Oxide Primer RO-350 delivers high-performance rust prevention through advanced hematite oxide pigment technology combined with fast air-dry phenolic-modified alkyd resin. This professional-grade primer provides exceptional protection against rust on compromised metal surfaces as the critical first step before topcoating.

Professional contractors choose RO-350 for its superior rust-holding and reformation capabilities. No primer works better at stopping rust progression and creating the perfect foundation for long-lasting topcoat adhesion. When metal surfaces have been compromised by corrosion, RO-350 is the first step in professional rust-proofing systems.

Advanced Hematite Oxide Technology:

✓ 99% UV Ray Blocking - Heavy hematite oxide pigment creates anti-corrosive barrier against damaging ultraviolet rays

✓ Superior Rust Control - No primer works better at holding back and reforming rust on compromised surfaces

✓ High-Performance Formula - Fast air-dry phenolic-modified alkyd resin for professional durability

✓ Exceptional Adhesion - ASTM D3359 5B rating (100%) to most metal surfaces including treated and untreated steel

✓ Professional Speed - 15-minute recoat window keeps projects moving efficiently

✓ Maximum Coverage - 50-60 square feet per can at 1 mil thickness

✓ Universal Application - Apply by rag, brush, roller, or sprayer for any project size

✓ Complete Rust-Proofing - Essential foundation step for professional anti-corrosion systems

The bottom line: While standard primers merely cover rust, RO-350's hematite oxide technology actively blocks UV damage and reforms rust for long-term corrosion control. Professional results require professional chemistry.
