What You'll Learn
Application and preparation
Firstly, it is imperative to drain the fuel tank and remove it from the vehicle. The tank must be free from any fuel before proceeding. Next, you need to clean the tank thoroughly. This involves removing any internal components, plastic components, old sealers, and loose rust. You can use a pressure washer or a solution of warm water and cleaner degreaser to remove gum, varnish, or sludge from the tank. It is important to note that POR-15 Fuel Tank Sealer does not adhere well to plastic, so ensure all plastic parts are removed or protected.
After cleaning, you should neutralize any remaining rust and prepare the metal surface for the sealer. This is done by applying POR-15 Metal Prep, which is a metal etching rust neutralizer. It dissolves rust, coats the tank with zinc phosphate, and etches the metal to improve adhesion for the sealer. It is important to follow the directions on the Metal Prep product to ensure proper use.
Once the tank is clean and prepared, you can apply the POR-15 Fuel Tank Sealer. Follow the directions on the product for application instructions, ensuring you wear proper personal protective equipment and work in a well-ventilated area. After application, allow the sealer to cure thoroughly for the best protection.
Additionally, it is worth noting that preparation and proper mixing are crucial for the success of this product. Users have reported positive results when taking the time to prepare the surface and mix the product correctly. It is also important to wear gloves and protect your skin when using this product, as it can be difficult to remove once hardened.

Sealing effectiveness
POR-15 Fuel Tank Sealer is a high-tech sealer designed for metal surfaces. It is formulated to be impervious to all fuels, including diesel, E10 ethanol, and high-alcohol content fuels. The sealer is applied as a coating to the inside of the fuel tank, creating a barrier that prevents rust, corrosion, and small fuel leaks.
The sealing effectiveness of POR-15 Fuel Tank Sealer is attributed to its ability to bond strongly with the metal surface of the fuel tank. To achieve optimal adhesion, the fuel tank must be thoroughly cleaned and prepared before applying the sealer. This includes removing any plastic parts, contamination, loose rust, and old sealers. It is recommended to use POR-15 Cleaner Degreaser to remove grease, oil, and surface debris, followed by etching the metal surface with POR-15 Metal Prep, which coats the tank with zinc phosphate to enhance adhesion.
The sealer's effectiveness also relies on proper application techniques. After cleaning and preparing the tank, it should be drained, rinsed with water, and allowed to dry completely. Once dry, the entire can of POR-15 Fuel Tank Sealer is poured into the tank, coating all surfaces. The tank is then drained to remove excess sealer, and fuel preservation and stabilizer products are recommended to maintain the fuel system and prevent "stale gas" issues.
The sealing effectiveness of POR-15 Fuel Tank Sealer is evident in the positive testimonials from users. Many customers have reported successful results in sealing small leaks, stopping rust and corrosion, and restoring old fuel tanks. Some users have mentioned that the sealer has lasted for almost 20 years in their vehicles, demonstrating its long-lasting protection.
However, it is important to note that some reviews highlight the importance of proper preparation and application. Tank liners and sealers may eventually fail, especially if the surface is not properly prepped or if the tank is not kept full or empty for extended periods. Therefore, following the manufacturer's instructions and allowing adequate curing time are crucial for achieving optimal sealing effectiveness with POR-15 Fuel Tank Sealer.

Durability
The POR-15 Fuel Tank Sealer is a high-tech product formulated for metal surfaces and designed to be impervious to all fuels, including diesel, E10 ethanol, and high-alcohol content fuels. It is available in 8 fl oz, 1-pint, and 1-quart containers. The product is marketed as a gas tank liner and fuel tank coating that can stop rust, corrosion, and small fuel leaks.
The durability of the POR-15 Fuel Tank Sealer is a key consideration for potential users. While some customers have reported excellent durability, with one user claiming that the product has lasted for almost 20 years in their fuel tank, others have experienced mixed results. Some customers have reported good protection, while others have noted issues with cracking and leaks.
The key to ensuring the durability of the POR-15 Fuel Tank Sealer appears to lie in the preparation and application process. It is essential to follow the manufacturer's instructions carefully and ensure that the fuel tank is properly cleaned and prepared before applying the sealer. This includes ensuring that the tank is free from plastic parts, contamination, and loose rust, and that it is structurally sound. Proper preparation of the metal surface is critical to achieving a strong bond between the sealer and the tank.
Additionally, it is important to allow adequate time for the coating to cure completely. One user noted that the product can take some time to fully cure but becomes "hard as nails" once cured. Another user emphasized the importance of proper preparation, stating that the sealant takes 48 hours to fully set.
While the POR-15 Fuel Tank Sealer is marketed as a durable solution for fuel tank sealing and rust prevention, it is important to recognize that all tank liners will eventually fail, as noted by a professional bike restorer. Therefore, proper maintenance and periodic reapplication of the sealer may be necessary to maintain the durability and effectiveness of the product over the long term.

Safety precautions
When using the POR-15 Fuel Tank Sealer, it is important to take several safety precautions to ensure your well-being and the best possible outcome for your project. Here are some detailed instructions and safety measures to follow:
Preparation and Safety Gear:
Before starting the sealing process, it is crucial to wear protective gloves and ensure that the product does not come into contact with your bare skin. POR-15 Fuel Tank Sealer is challenging to remove from the skin once it has hardened, so immediate washing is necessary if it comes into contact with your skin. Ensure you have a well-ventilated workspace to avoid inhaling any potentially harmful fumes.
Fuel Tank Preparation:
The fuel tank must be free from contamination and structurally sound before applying the sealer. Remove all internal components, plastic parts, old sealers, and loose rust. Clean the tank thoroughly using a mixture of POR-15 Cleaner Degreaser and warm water to eliminate any gum, varnish, or sludge. You can add weight, such as a chain or nuts and bolts, inside the tank while shaking it to help dislodge stubborn debris. Ensure the tank is completely dry before proceeding.
Metal Preparation:
After cleaning, apply POR-15 Metal Prep to dissolve any remaining rust, coat the tank with zinc phosphate, and etch the metal. This step is crucial for better adhesion of the sealer to the tank. Ensure that all surfaces are coated evenly.
Sealing and Curing:
Once the tank is prepared, pour in the entire can of POR-15 Fuel Tank Sealer. After coating all surfaces, drain the tank for about an hour to remove any excess sealer. Allow adequate curing time for the sealer to harden and achieve impervious protection from fuel and corrosion.
Post-Sealing Care:
After the sealer has cured, use fuel preservation and stabilizer products to maintain your fuel system and prevent "stale gas" issues. Regularly inspect your fuel tank for any signs of leaks or corrosion. If you need to remove the sealer in the future, be aware that it is challenging to dissolve, and mechanical methods such as grinding, sanding, or sandblasting may be necessary.
Always refer to the manufacturer's instructions and take your time with each step to ensure a safe and successful sealing project.
