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!

* 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.

    This Stuff!
    Really good stuff, I would like to echo what most are saying.1. You're going to destroy the can & lid opening it. I have the fancy lid opener, it just inverts the cans Male / female.2. Put something down, because it's probably not coming off.3. Use gloves, this stuff has a mind of it's own, comes after you like you're Tasha Yar.4. Use those cheap sponge brushes, you can't clean this stuff easily.5. Use Amazon plastic bubble packaging to do small stuff, it peels right off, unlike cardboard.. from experience.6. Use the small cans and open as you go, this stuff is moisture based and dry up very very very fast.7. Pour contents into something different, you really can't get a wider brush in the can, I used old plastic resealable containers, that also helped when I needed to stop for a second.8. It's totally worth the money..Stuff is great,

    I've been a long-time user of POR-15 on my car's underbody and suspension parts as I live in the rust belt of the US. The smaller 2 oz. cans of POR-15 are perfect for yearly touch-up of components under the car to prevent rust, or control rust that has already started and needs to be arrested. I recently bought a 1998 car that spent it's life in WV and I used one 2 oz can under the car to cover most of the frame rails and the rear differential and a few axle parts. The semi-gloss black looks good. My experience with POR-15 is that it will stand up to the winter salts for 2-3 years before a touch-up is needed. Good kit.

    Easy to apply, dries quickly and durable. Must be top coated for UV resistance. Only downside is the cans were sealed shut with paint before we opened them. After opening the lids were turned inside out and couldn’t be resealed. The small cans are definitely the way to go since they are so hard to reopen (even when you carefully clean the lid and can lip). We used a glass jelly jar to save leftovers.

    5.0 out of 5 stars POR-15: A Mechanic's Review for Long-lasting Rust Prevention
    Reviewed in the United States on April 30, 2024
    Verified Purchase
    As a mechanic, I've seen my fair share of corrosion damage. That's why I was excited to try POR-15, a highly-rated corrosion prevention coating. Here's my experience after using it for months at work and on personal projects:

    Pros:

    Excellent Adhesion: This stuff sticks to practically anything! I've been impressed with its ability to bond to various surfaces.
    Durable Finish: The finish looks great and seems very tough.
    Versatile Application: While the product allows application on various surfaces, I recommend some prep work beforehand for optimal results and a longer-lasting, professional look.
    Overall, POR-15 is a fantastic choice for anyone who needs serious rust prevention. It's easy to use, highly effective, and delivers a great-looking finish with a little prep effort.

    Here's who might benefit most from POR-15:

    Mechanics or DIYers dealing with rust issues
    Anyone looking for a durable and versatile corrosion protection coating

    Tip: While not strictly necessary, following the recommended prep work can significantly enhance the final outcome

    Reviewed in the United States on November 12, 2016
    Verified Purchase
    While I needed to deal with some serious "rust remediation" issues with the under-body and frame of my '02 Dakota (after I neglected it through a couple of Northeastern winters), my initial use for POR-15 was the perpetually rusting brake calipers and drums: None of the paint products I had previously used held up for more than 6 to 9 months before discoloration and rusting set in again - even when applied to new (and clean) parts.

    The only prep I did was to use a hand-held wire brush to remove loose scale / dirt, and degreased with aerosol brake parts cleaner. For my purposes, sponge brush applicators have generally been best when used with a "dabbing" motion on rough-castings to provide uniform coverage and penetration. As has been noted by others: You may be pleasantly surprised by the coverage you can achieve. I was able to apply a single coat to both calipers / support brackets, both drums / backing plates, and the lower control arms with a single 4 oz. can. I used about 6 sponge brushes (2 inch) to do this, so I suggest buying them in bulk.

    I initially purchased the 6-pack of 4 oz. cans due to concerns about shelf-life for the larger quantities, but learned from experience that the iron oxide acts as a catalyst for POR-15, so applying it straight from a can gradually introduces small amounts of rust to the remaining material, causing it to thicken over the course of a few days use. This may also be a reason for limited shelf-life issues, so you should dispense POR-15 to another container for a small job, or a for larger task performed over a period of time.

    What truly impressed me was durability: I had removed the brake drums and applied the POR-15, allowing 24 hours for it to "cure". In the meantime, I decided to replace the brake shoes. Once cured, the POR-15 had a uniform gloss black appearance, although I could detect a faint reddish hue in bright sunlight. This was fine with me, as it was only a single coat, and I was curious as to how it would hold up over time. I reinstalled the drums, and then had some issues with excessive drag while adjusting the new shoes. When I tried to remove the drum to check my installation, it didn't budge, so I used a hammer around the rim to assist - and then realized that wasn't a very bright idea with any painted surface - but the POR-15 simply conformed to the obvious dings, and refused to come off even when I tried scuffing the dings with a wire brush.

    From experience: The only "problems" I have had have been prep-related - all surfaces to be treated need to be THOROUGHLY degreased, and all loose material must be removed. Use good portable lighting if needed. Be especially observant to remove rust "blisters" that form on areas like frame rails - using a cupped twisted strand wire brush on a grinder will frequently only "polish" the blisters without removing them, and rust will start to show again at those spots within a few months. The better tool to use is an air-powered needle scaler that will break the blisters. I've seen that with areas that were properly cleaned and prepped the POR-15 even resists passes with the scaler or powered brush.

    At this point, after 6 months and multiple pressure washes, the POR-15 treated brake parts still have a fresh appearance, with no rust returning. I have only a few remaining areas under the truck to treat, and I still have a can left from the 6 pack. I won't hesitate to reorder more if needed, and highly recommend it, along with the POR Patch, as effective solutions for persistent rust problems.

    EDIT : if you have a partial can , I recommended putting some tape on the lid ro help seal and put it in the fridge to keep it cool, I did that and it was there for 2 months and was still good when I went to use it

    This was my first experience with por 15 rust preventative, and I'm glad to say if was a positive .

    Don't let the price scare you, I bought the 6 pack of 4oz cans and 1 can will cover a lot of area with 2 coats it covers very well.

    I will likly be buying buying a gal next since I think that's the best deal, I was a little concerned at first over reading people's ishues with storage but if u have any experience with paint cans it should be an ishue... keep the rim clean and make sure rhe lide has a good seal and it shouldn't be a ishue

    I used a spung brush, seemed ro work the best

    The surface of the can will harden, even with the lid back on. You could purge the can with CO2 or nitrogen, but that isn't very practical. The small cans will minimize this waste. You can break through the skin with a screw driver, and if you come back in a few months and found it impossible to get to the remaining paint -- at least you only wasted a little.

    A little of this goes a long way on metal, so the quart size is overkill for small jobs.

    POR is a super tough paint for metal.

    4.0 out of 5 stars La meilleure peinture antirouille!

    J’utilise cette peinture sous la voiture, elle est excellente! Pour avoir utilisé plusieurs produits, appliqué directement sur la rouille c’est celle qui dure le plus longtemps. Maintenant je l’utilise en petits pots car une fois le contenant ouvert, elle durcit très vite et avec un grand pot j’ai des pertes. Un seul point faible, c’est le prix qui en fait un produit dispendieux. Mais combien de pièces rouillées sauvées grâce à ce produit.
