    item(s): PB-3SS

    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!

    Good Service

    POR15 Cures from atmosphere, air and moisture. Keep the lid on as much as possible,
    pour POR15 into a paper cup and put the lid over the can to only allow minimum exposure to atmosphere.
    When you are done painting, use a plastic sheet over the can then close with the can top.
    PUT the can in a plastic bag and store the can UPSIDE DOWN. Keeping in a tray
    would be a good idea in case some of the POR15 leaks out.

    Great Results!

    I used this on my 2002 Chevy Silverado 1500 Extended Cab. I live in New England, so major rust issues. Removed the bed, gas tank, leaf springs, and shocks; Followed the instructions. See the before and after pictures. Amazing results. very happy with the product; next summer I will take the cab off and restore the front of the truck!

    Awesome Product

    Removed rust from my boat trailer axes and used all three products. Easy to use just follow directions. Drying time depends on weather. I gave my trailer axe two coats. Easy to apply with a brush. Make sure you have adequate ventilation. Tailer looks better than new with a Hard Shinny Coat.

    Outstanding Product, You can Store it after use, try this advice

    I have used Por15 on a lot of projects. VERY TOUGH Layer after cured. It is affected by UV
    and if not protected will wear off in a few years time if you do not coat it with a Top Coat Paint.
    HUGE WARNING, Don't get POR15 on any moveable parts, hinges, or bolts that you may want
    to remove later.
    Once POR15 cures, it will lock any seams, bolts, nuts into basically ONE WHOLE PIECE.
    MAKE SURE the surface is clean, Grease and Oil free. Use the cleaners.

    POR15 goes on like a very fluid paint, IT WILL RUN if you apply too much at once so
    be watchful. Be cautious as you can't brush POR15 too much during the dry period as
    it begins to skim over, brushing will mess it up. Any voids, seams spaces between
    moving parts WILL BE SEALED AS ONE SOLID PIECE. fair warning.
    I am always using POR15 for some project to prevent rust or to stop rust. You can
    just open the can and use a little if you store it carefully.

    -- FOR STORAGE --
    POR15 Cures from atmosphere, air and moisture. Keep the lid on as much as possible,
    pour POR15 into a paper cup and put the lid over the can to only allow minimum exposure to atmosphere.
    When you are done painting, use a plastic sheet over the can then close with the can top.
    PUT the can in a plastic bag and store the can UPSIDE DOWN. Keeping in a tray
    would be a good idea in case some of the POR15 leaks out.

    The POR15 in the can WILL SKIM OVER on the top, the side with the Air inside.
    IF you store a used POR15 can Top side UP, the top of the POR15 WILL skim
    over. If the skim layer is not too thick, you can break it and access the product
    under the skim layer. Better Idea to store the can upside down and let the
    skim layer form on the bottom side of the can.
    The POR15 should be usable when you open it again, unless you allowed long term exposure
    to the atmosphere when you were using it. If the POR15 had a long term exposure to the
    atmosphere, then it may cure completely in the can no matter what.

    WHEN USING, wear old clothes and gloves.
    POR15 on skin is difficult to get off and you may end up wearing it off. Try kerosene on a
    paper towel to get most of it off the skin.
    You CAN NOT get POR15 off of clothes or concrete and it will take literally YEARS for the
    POR15 to wear off of CONCRETE.

    Metal that is media blasted provides the best surface for coatings. If not possible, remove all built-up dirt, loose rust, and paint. Note that if you leave old paint behind, the rust preventive can only adhere as strongly as the paint it is applied over. This generally is not as strong as applying to prepped and scuffed-up bare metal.

    These products should only be handled when wearing latex gloves, eye protection, and NOSHA approved respirator. Always work in a well-ventilated area. 

    Step 1. Apply our POR-15 Cleaner Degreaser to a surface, agitate the surface with a scuff pad or brush and keep wet 10-15 minutes then rinse thoroughly with water and allow the surface to dry. Repeat if surface is still oily or greasy. It is important not to allow the product to dry on the surface prior to rinsing with water. POR-15 Cleaner Degreaser is a heavy duty water soluble cleaner that may be used over metal, wood, fiberglass, vinyl and concrete.

    Step 2. Apply POR-15 Metal Prep to the bare metal surface, keep wet 10-15 minutes then rinse thoroughly with water and allow the surface to dry. It is important not to allow POR-15 Metal Prep to dry on the surface prior to rinsing with water. Once dry the surface may show a flash rust or white powdery residue this is perfectly normal. POR-15 Metal Prep provides the best surface profile and greatly improves paint adhesion to any type of metal surface for opaque paints and coatings.

    Step 3. Wearing gloves and a properly fitted NOSHA approved respirator is recommended when applying POR-15 Rust Preventive Coating. Do Not shake. Mix by stirring until all solids at the bottom of the can are dissolved. Mixing may be done with a drill mixer on slow or by hand. It is recommended to apply two thin covering coats of POR-15 Rust Preventive Coating. Apply the first coat to the properly prepared substrate with a brush, roller, or HVLP (proper PPE required). Apply the second coat when the first coat is dry but still slightly tacky to the touch. If POR-15 Rust Preventive Coating is applied too heavy, brush marks may result in the finish. Do not apply this product if the humidity is above 70%. If the humidity is too high POR-15 Rust Preventive Coating will surface dry too quickly which may result in small bubbles in the finish. POR-15 Rust Preventive Coating requires an opaque topcoat only if exposed to direct sunlight. Best chemical adhesion to POR-15 Rust Preventive is when it is dry but still tacky (it has a finger drag). If the rust preventive is already completely dried or cured, you must scuff the surface with a maroon pad or 320-380 grit sandpaper for mechanical adhesion of a topcoat.

    If your project will be exposed to U.V. light, topcoat it with POR-15 TopCoat, Engine Enamel, Caliper Paint, Detail Paint, or 2K Urethane industrial topcoat. You can topcoat with most other UV safe opaque paint as well.
