POR-15® 45408 High Performance Rust Preventive Permanent Coating

POR-15 Rust Preventive is a single-component urethane coating that seals rusted or bare metal surfaces against moisture, chemicals, and salt corrosion. This 16 oz pint applies directly to metal without surface prep, curing to a rock-hard, non-porous finish that resists abrasion, impact, and temperatures up to 450°F. The waterproof barrier prevents rust recurrence while accommodating metal expansion and contraction. Exceeds 2000-hour salt spray testing for long-term corrosion protection.
