The ultimate rust preventive system for permanent corrosion protection. Shields metal in just 3 easy steps, clean it, prep it, and coat it. Better than any rust paint available! The POR-15 3-Step Stop Rust System is designed to stop rust on metal surfaces and ensures the best results when applying POR-15 Rust Preventive Coating. Prepare and prime bare metal or directly paint surface rust with confidence. The clear-cut process when using this rust stopper for metal allows for the proper cleaning, prepping, and coating of metal to create a non-porous surface to seal and protect metal from water, chemicals, salt, fertilizer, acids, alkalis, and other corrosive contaminants. Black and Gray Rust Preventive Coatings are non-conductive and good for EV conversion applications. A topcoat is required if exposed to UV light. Check out this rust stop undercoating now! The components of the 3-Step Stop Rust System Step 1: POR-15 Cleaner Degreaser (Formerly Marine Clean) removes grease, oil, dirt, and grime in one application without leaving residues, noxious fumes, or flammable solvents. Step 2: POR-15 Metal Prep (Formerly Prep & Ready) etches to provide the best adhesion for POR-15 Rust Preventive Coating on metal surfaces. Step 3: POR-15 Rust Preventive Coating is a high-tech, high-performance rust preventive coating designed for application directly on stable rust or seasoned metal surfaces. Permanent rust protection with a hammer-tough finish resistant to acids, alkalis, oils, and repels all fuels. Step-by-step Restoration Before: Heavily rusted diamond-plate pickup truck beds can be a problem, fix them permanently with the POR-15 3-Step System. Step 1: Clean it! Remove loose rust and degrease the surface with a water-based Cleaner Degreaser Step 2: Prep it! Neutralize rust and etch with Metal Prep. Step 3: Coat it! After thorough washing and drying, coat with POR-15 Rust Preventive Coating, right onto the rust! For areas exposed to U.V. light: Topcoat with Top Coat, 2K Industrial Urethane, or other UV safe opaque paint of your choice. After: Now you have a PERMANENTLY repaired truck bed, that won't rust again. POR-15 Rust Preventive Coverage • Pint 25 sq ft with two coats • Quart 50 sq ft with two coats • Gallon 200 sq ft with two coats POR-15 Rust Preventive Testing Results Structural Strength Measures ASTM C-580 Flexural Strength - measures flexural strength and modulus of elasticity. 5,200 pounds per square inch ASTM C-579 Compressive Strength - measures compressive strength, the capacity of axially directed pushing forces. 12,500 pounds per square inch - Verified. Not tested to failure. ASTM C-307 Tensile Strength - measures the tensile strength of cured chemical-resistant materials. 3,200 pounds per square inch ASTM D-4541 Bond Strength To Concrete - measures the strength of coatings bond to concrete. Concrete fails before POR-15 Rust Preventive Coating. It exceeds the tensile strength of concrete Abrasion Resistance ASTM C-501 Taber Abraser - abrasive wear by determination of the loss of weight resulting from abrasion. In two separate tests, POR-15 Rust Preventive had: No loss after 1,000 cycles with a 1,000 gram abraser Loss after 10,000 cycles with 1,000 gram abraser = 0.09 grams Weather Resistance Weatherometer - accurate weather resistance indicator of cycling of conditions. The cycle is 30 mins at 135 degrees F, 30% relative humidity and 30 mins at 75-80 degrees F, 100% relative humidity 1,000 hours of exposure equals 5 years of simulated exposure in the Rocky Mountain region. There was no change in the 3 panels coated with POR-15 Rust Preventive Coating exposed for 2,000 hours. ASTM B-117 Salt Spray - specimens exposed at specific locations and angles. Created a 100% relative humidity condition in the exposure zone. Two separate B-117 tests. One with new bare steel and the other with rusted steel. Both were coated with POR-15 Rust Preventive Coating. No change in 3 panels of new steel exposed for 250 hours at 98 degrees. Thickness = 2 mils No change in 3 panels of rusted steel exposed for 1000 hours at 98 degrees. Thickness = 2 mils Chemical Resistance Chemical Bath Test - After 200 hours of soaking in the following chemical bathes, panels coated with POR-15 Rust Preventive Coating experienced no changes: 10% hydrochloric acid, 50% sulphuric acid, 55% chromate, 85% phosphoric acid, 10% sodium hydroxide 98% methanol. Raw Sewage Test - A metal box that houses a filter for raw sewage in a treatment facility was coated with POR-15 Rust Preventive. After a year of service, no undercutting or rusting was present on the housing. Impact, Porosity, and Temperature Tests Mil-D-3134J Impact Resistance - POR-15 Rust Preventive Coating exceeds standards. ASTM C-413 Water Absorption - method covers the determination of absorption of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes. 0.0001 maximum NACE Stand TM0174 - 0.00 POR-15 Rust Preventive Coating is a non-porous coating. Temperature Resistance - POR-15 Rust Preventive Coating is temperature resistant up to 450° continuously. Test showed no adhesion lost at 450° F for 10 hours.
