About this item

  • ✅ 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.
  • ✅ WHEN DO I NEED THIS – Automotive, Farm, industrial, commercial marine, and construction industries all use POR-15 Rust Preventive Coating to protect valuable equipment against rust, abrasion, & corrosion. Our coating has excellent surface tolerance on porous surfaces, such as wood, fiberglass, concrete, bricks, and more!
  • ✅ OUR SATISFACTION COMMITMENT – At POR-15 we strive to bring the ultimate in rust prevention. Known for the unbeatable 3-step stop rust system, POR-15 is trusted by DIY & Professionals. We are committed to innovation, quality control, and excellent customer service.

POR-15 Rust Preventive Coating

Stop Rust and Corrosion Permanently

POR-15 Rust Preventive Coating REALLY Stops Rust Permanently! POR-15 Rust Preventive Coating is designed for application directly on prepped rusted, sandblasted, and seasoned metal surfaces. It dries to a rock-hard, non-porous finish that won’t chip, crack, or peel, and it prevents rust from recurring by protecting metal from further exposure to moisture.

Provides rust protection with a hammer-tough finish.

  • Seals rust permanently
  • No need to remove rust before applying
  • Lead-Free
  • For metal substrates
  • * Exceeds 2000 hour salt spray test
  • * Tested over 450°F / 232°C
  • Repels fuels and oils
  • * Resistant to most acids and alkalis

Proper application of POR-15 Rust Preventive Coating using the 3-Step System

POR-15 Cleaner Degreaser

POR-15 Metal Prep

POR-15 Rust Preventive Coating

POR-15 Top Coat

Step 1: Clean it!

Remove loose rust and degrease surface with water-based POR-15 Cleaner Degreaser

Step 2: Prep it!

Neutralize rust and etch it with POR-15 Metal Prep. Thoroughly wash with water and dry.

Step 3: Coat it!

When surface is dry, apply POR-15 Rust Preventive Coating right onto the rust with two or three thin coats!

For areas exposed to U.V. light - Topcoat it

Topcoat with POR-15 Top Coat, POR-15 2K Urethane, or other top coat of your choice. Top Coat the POR-15 Rust preventive while it is tacky for proper adhesion.

* LABORATORY TEST RESULTS

POR-15 Rust Preventive Coating was tested for 168 hours at 97°F in a condensing humidity salt spray (ASTM B117). At the end of the test period, coated steel was free of rust or pitting. Acid and alkali resistance tests performed found panels coated with POR-15 Rust Preventive Coating to be impervious to gasoline, oil, chromic acid, hydrochloric acid, phosphoric acid, sodium hydroxide, caustic soda, 50% sulfuric acid, and 50% hydrofluoric acid. POR-15 Rust Preventive Coating was applied over a rusty substrate as a finish coat (approximately 23 mils dry film thickness). The coating showed essentially no undercutting at the scribed area after 2000 hours in a weatherometer*.

A 2 mil thickness of POR-15 Rust Preventive Coating was applied to lightly rusted steel and then exposed for 1000 hours to a salt spray. At the end of the test period, no undercutting was observed at the scribed area. Recoatability is excellent. Laboratory tests have shown very good adhesion when applied up to 14 days after application of the first coat. In an actual Field test, a topcoat was applied 6 weeks after the first coat had been applied, and the intercoat adhesion was excellent as determined by a crosshatch tape test. A metal box used as a filter for raw sewage was coated with POR-15 Rust Preventive Coating and placed in service within a few hours after the interior and exterior were coated. No visible rusting occurred at the welded areas after a six month exposure.

A POR-15 Rust Preventive Coating coating was subjected to 450°F for 10 hours; it remained hard and showed no apparent loss of adhesion. A panel subjected to elongation was pulled beyond the yield point of the base metal without affecting the POR-15 Rust Preventive Coating coating.

Product Description

POR-15 Rust Preventive Coating is the Only Product that REALLY Stops Rust Permanently! POR-15 Rust Preventive Coating is designed for application directly on prepped rusted, sandblasted, and seasoned metal surfaces. It dries to a rock-hard, non-porous finish that won’t chip, crack, or peel, and it prevents rust from recurring by protecting metal from further exposure to moisture.

Irritated…
First off, this product is awesome, secondly my major complaint is the lid will not come off the can and if I try harder, it is going to destroy the lid and never reseal again, wasting the product, and this stuff is too expensive to waste. As an avid user of this product, I have long been aware that you must use food wrap between the lid and can or else the lid will permanently become glued to the can like this brand new lid/can is. I’m guessing this can must’ve been sitting on the shelf in the warehouse for too long or when it was filled at the factory they got some product in the groove where the lid goes into the can. I wish they would put a plastic barrier between the lid and can from the factory so this doesn’t happen or at least ship a spare lid with the can. Now my project I was hoping to have done in a couple days is going to take much longer as I attempt to communicate with the company because this product CANNOT BE RETURNED!! And likely they will suspect me of using some product and trying to get it for free. All I want is to complete my project… This is highly irritating.

5.0 out of 5 stars Slick and hard finish.
Reviewed in the United States on December 30, 2023
Used this on the bottom of a 60" three blade mower deck. Deck has 7 seasons and about 400hrs of use before this. Used twisted wirewheel in a grinder to cleanup, then used the etching POR15 surface prep (I skipped the cleaner because it was grease free) then did two coats of the product - brused on with a cheap set of brushes, was easy to apply. Overall I'm very happy with the results, however next winter will be a good gauge as to how well it'll hold up to the harsh life under a mower deck. I update the review next year.
