The kit seals leaks and stops rust and corrosion in metal fuel tanks
The POR-15 Fuel Tank Repair Kit is a comprehensive solution for sealing leaks and preventing rust and corrosion in metal fuel tanks. The kit is suitable for use on automotive, agricultural, and industrial machinery gas or diesel fuel tanks.
One of the key advantages of the POR-15 kit is its ability to seal leaks and prevent future corrosion. The kit includes a quart of sealer, which is designed to permanently seal pinhole leaks and create a tough, durable barrier that is impervious to fuels, including Stage II fuels with higher alcohol content. The sealer provides superior strength and fuel resistance, ensuring that your fuel tank remains protected.
To ensure the effectiveness of the sealer, the kit also includes cleaning and preparation products. The POR-15 Cleaner Degreaser helps remove gum, varnish, sludge, and other contaminants from the fuel tank. It is mixed with hot water and poured into the tank to dissolve and remove any built-up residue. After cleaning, the tank is drained and rinsed to ensure a thorough cleaning.
The kit also includes POR-15 Metal Prep, which is used to remove rust and prepare the metal surface for sealing. It coats the tank with zinc phosphate and etches the metal, improving the adhesion of the sealer. This step is crucial for ensuring the effectiveness and longevity of the sealed fuel tank.
In addition to the sealer, cleaner, and metal prep, the kit provides detailed instructions, a brush, and reinforcing fabric. The instructions guide users through each step of the tank restoration process, ensuring proper application and curing of the sealer. The kit's comprehensive approach makes it a reliable choice for repairing and protecting metal fuel tanks from leaks, rust, and corrosion.

The kit includes a range of products to thoroughly clean, prepare, and seal the tank, ensuring effective and long-lasting results.
One of the critical steps in the tank restoration process is cleaning and neutralising the tank to improve sealer adhesion.
