POR-15 Rust Preventive Coating is a high performance coating designed for application directly on prepped rusted or seasoned metal surfaces and will stop rust permanently. 

POR-15 Rust Preventive Coating is non-porous and seals and protects many surfaces from water, chemicals, salt, and other corrosive contaminants and is able to be painted over rust. 

POR-15 Rust Preventive Coating is an effective anti-corrosive and rust preventive coating that offers superior chemical resistance due to its dense, cross-linked molecular composition and non-porous attributes.

The secret lies in POR-15 Rust Preventive Coating's curing process. Most paints dry through evaporation, but POR-15 Rust Preventive Coating dries faster when moisture is present. It has the opposite chemistry of ordinary paints.

Now add to that POR-15 Rust Preventive Coating incredible hardness, toughness, and flexibility and you have a coating that is practically indestructible. 

POR-15 Rust Preventive Coating is a permanent rust repair great for auto frame and chassis restoration, protecting valuable equipment against rust and corrosion.

Use POR-15 to protect expensive and valuable equipment against rust and abrasion.
POR-15 also has excellent "surface tolerance" which means it works very well on porous surfaces.

Use POR-15 Cleaner Degreaser and POR-15 Metal Prep to properly get your surface ready for the POR-15 Rust Preventive Coating. You'll be amazed at the toughness!


  • Double the solid content of most paints
  • Compatible with all paint systems
  • Tested over 450°F / 232°C 
  • Exceeds 2000 hours salt spray test
  • Self-leveling
  • Hammer tough
  • Single Component
  • Dries faster in humid conditions
  • Repels all fuels and oils
  • Resistant to most acids and alkalis.


  • Automotive - chassis, doors, floors, trunk areas, suspension, engines and fuel tanks
  • Industrial - heavy equipment, truck components, trailers, fuel storage, rebar, steel forms, concrete, storm gates, transformers
  • Marine - decks, bilges, hulls, pipes, chain lockers, masts
  • Also excellent for sealing and repairing fiberglass


  • 1 quart covers 96 sq. ft. / 946mL covers 8.9m² (single coat on most metals - but we recommend applying two coats in most applications)
  • For porous surfaces like wood & concrete, coverage will be about 20% less

Size: Quart = 946mL

Technical Data Sheet - POR-15 Rust Preventive Coating

Safety Data Sheet - POR-15 Rust Preventive Coating Silver



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 far exceeds the tensile strength of concrete


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

    Weatherometer - accurate weather resistance indicator of cycling of conditions. The cycle is 30 mins sun at 135 degrees F, 30% relative humidity and 30 mins dark 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 are exposed at specific locations and angles. It creates 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 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 viable undercutting or rusting was present on the housing.


    Mil-D-3134J Impact Resistance - POR-15 Rust Preventive Coating exceeds standards.

    ASTM C-413 Water Absorption - method covers the determination of the 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. A test showed that no adhesion was lost at 450° F for 10 hours.
