    POR-15 Fuel Tank Sealer

    POR-15 Fuel Tank Sealer was Formulated for metal and developed as a high-tech sealer that is impervious to all fuels, including the diesel, E10 ethanol, and high alcohol content fuels. This gas tank sealant comes in a silver color and has superior strength with fuel resistance. Also, this fuel tank coating acts as a liner and stops rust, corrosion, and small fuel leaks. Fuel tanks must be free from plastic parts, contamination, and be structurally sound before applying sealer. Gas tanks should be free from loose rust, old sealers, cleaned with POR-15 Cleaner Degreaser, and etched with POR-15 Metal Prep for best adhesion.

    Color: Silver

    Coverage of this Gas Tank Sealer:

    • 8 fl oz is enough to coat the inside of a 6 gallon fuel tank
    • 32 fl oz (quart) is enough to coat the inside of a 25 gallon fuel tank

    Formerly U.S. Standard Fuel Tank Sealer

    Step 2: Pour the entire bottle of POR-15 Metal Prep to dissolve rust, coat the tank with zinc phosphate, and etch the metal for better adhesion of the sealer.

    POR-15 as good as it gets!

    Have used this product several times now.
    Tractor tanks, motorcycles and storage tanks, this is my “Go-To” for sealing and cleaning tanks. Follow the directions and you can not go wrong.

    Worked really well

    No thinning needed leveled out very nicely and low odor. Also no reason to empty entire contents into a small motorcycle tank. Directions probably just need to be updated directing to use what's needed for a good uniform coat.

    Great but I screwed up

    Great product did very well on the first fuel tank read the directions, but totally missed the part of wearing gloves and do not for whatever reason ever get it on your bare skin or your arm. It will literally not come off. You must wash it absolutely immediately once it is hardened, the only way you can take it off is voice, a pair of tweezers and very small increments. Totally my fault, brake cleaner, nail polish paint thinner, and other soaps and sandpaper will not absolutely not remove this from your skin.

    POR 15 tank sealer

    I have used your other paint and it works really good. I have not gotten around to using the tank sealer yet.

    - POR-15 Fuel Tank Repair Kit Directions

    It is important to understand each product in your repair kit and how it works. Proper chemical interaction is essential for achieving the best possible bond of the sealer to the inside of the tank. Fuel Tank Sealer does not adhere well to plastic. If your fuel tank contains plastic components inside, they should be removed before applying Fuel Tank Sealer.

    Please remember these instructions are general guide lines only and cannot and do not cover every application and environment. If you remain unsure as how to proceed, please call toll-free for technical advice at 800-457-6715.
