About POR-15: A Century of Coating Innovation

Few brands have shaped the world of metal protection as profoundly as POR-15. POR-15 traces its roots back to 1923, when its parent company began life as a shellac and finishing-products manufacturer in the Bronx, New York. Decades of chemistry expertise culminated in a pivotal moment in 1978, when the company introduced its now-legendary moisture-cure rust preventive coating technology — a breakthrough that fundamentally changed how enthusiasts, professionals, and industries approach corrosion protection.

Today, POR-15 is headquartered in New Rochelle, New York, and its products are trusted on everything from museum-quality antique cars and award-winning restoration builds to government fleet vehicles, heavy farm equipment, and industrial machinery across more than 52 countries. The name itself — short for "Paint Over Rust" — reflects the brand's foundational philosophy: rather than requiring the complete removal of all rust before coating, POR-15's flagship formulas are engineered to be applied directly to stable rusted or seasoned metal surfaces.

What Makes POR-15 Different

The secret behind POR-15's performance lies in its unique curing chemistry. Unlike conventional paints that dry through solvent evaporation, POR-15 coatings cure through a moisture-driven reaction — meaning they actually harden faster in humid conditions. The result is a rock-hard, non-porous barrier that resists water, road salt, fuels, chemicals, acids, and UV exposure without cracking, chipping, or peeling.

POR-15 also designs its products to work as a complete, integrated system. The three-step "Stop Rust" process — clean, prep, coat — pairs the brand's dedicated Cleaner Degreaser and Metal Prep products with the core rust preventive coating, ensuring maximum adhesion and long-term protection. Whether used as a standalone treatment or as a foundation for a finish coat, each product in the lineup reinforces the others.

A Complete Range of Protective Products

Beyond its core rust preventive coating, POR-15 offers an expansive portfolio of specialized products. For chassis and underbody work, the brand's rubberized undercoating brings POR-15's proven rust preventive technology into a flexible, spray-applied form that deadens road noise and resists road salt and abrasion. Restoration builders appreciate the brand's broad range of spray paints and Top Coat finishes, which pair seamlessly with the core rust preventive system for a durable, UV-stable final appearance. Engine builders can turn to POR-15's dedicated engine paint line — a self-leveling, high-temperature enamel capable of withstanding sustained engine heat while delivering factory-correct color options for popular makes. For projects requiring more advanced formulations, the brand's specialty coatings range includes high-temp paints rated for extreme thermal environments, strip gels, patch compounds, and more.

Whether you are tackling a frame-off classic car restoration, refreshing a work truck's undercarriage, or simply protecting exposed metal before the next winter season, POR-15 offers a product engineered for the task.
