✅ WHY CHOOSE POR-15 RUST PREVENTIVE COATING – POR-15 is the gold standard in high performance coatings. Trusted by DIY and professionals to stop rust permanently by forming an impenetrable barrier that protects a variety of surfaces from water, chemicals, salt, corrosive contaminants and everyday wear and tear. No other paint, coating, or even powder coat can match POR-15 Rust Preventive Coating when applied using the 3-Step Stop Rust System.

✅ CURED BY MOISTURE – The secret strength lies in the curing process. Unlike most paints that dry through evaporation, POR-15 Rust Preventive Coating dries faster when moisture is present. It has the opposite chemistry of ordinary paints. Once cured, the coating forms an indestructible, hammer tough finish.

✅ APPLICATION - Remove grease, oil, and other foreign substances using POR-15 water-based Cleaner Degreaser followed with POR-15 Metal Prep to etch the surface and neutralize rust. Stir POR-15 Rust Preventive Coating thoroughly, DO NOT SHAKE. Always apply thin coats, minimum of two. May be recoated or top coated when dry to the touch, typically 2 to 5 hours. Topcoat when surface will have exposure to UV light.
