What You'll Learn

Application and use
POR-15 Fuel Tank Sealer is a high-tech sealer that is impervious to all fuels, including diesel, E10 ethanol, and high-alcohol content fuels. It is also resistant to all fuels, alcohols, and additives. It is specifically formulated to provide a permanent seal with superior strength and resistance to all types of fuels. The sealer is non-flammable and environmentally safe. It is also priced well and easy to use.
Before applying the sealer, it is important to clean the fuel tank thoroughly. This includes removing any fuel varnish or other coatings from the inside of the tank using a cleaner degreaser. It is also important to remove any loose rust and old sealers, as the new coating will not stick to gum and varnish. After the tank is clean, it should be drained and rinsed with water, and then allowed to dry completely.
Once the tank is dry, the next step is to use a metal prep to remove any remaining rust and to etch the metal for better adhesion of the sealer. This step is crucial, as it helps the sealer stick to the tank and provides a more durable finish. After the metal prep is applied, the tank should be drained again and rinsed to remove any residue.
Finally, the sealer can be applied. The entire can of sealer should be poured into the tank, and the tank should be rolled or rotated to ensure that all surfaces are coated. It is important to follow the instructions on the sealer and allow it to dry for the recommended amount of time before reinstalling the tank and filling it with fuel.
Some users have noted that the sealer can be difficult to remove from the skin and other surfaces, so it is important to wear gloves and cover the surrounding area with plastic or painter's tape. It is also recommended to have plenty of solvent and rags on hand during the application process.

Safety and flammability
POR-15 Fuel Tank Sealer is a non-flammable and environmentally safe product. It is formulated without Methyl Ethyl Ketone, a highly flammable and deadly carcinogen.
The product is safe to use on any type of fuel tank, including those with high alcohol content fuels, such as Stage II fuels, diesel, and E10 ethanol. It is also suitable for use on plastic components inside the fuel tank, but these should be removed before applying the sealer for the best results.
Before applying the sealer, it is important to follow the necessary preparation steps. These include draining the fuel tank, removing the tank from the vehicle, and cleaning out the tank to remove any gum and varnish. Failure to clean the tank first may result in the new coating failing to stick properly. After cleaning, the tank should be coated with zinc phosphate and etched with a product like POR-15 Metal Prep to improve adhesion.
It is important to note that POR-15 Fuel Tank Sealer can be difficult to remove from skin, so it is recommended to wear gloves during application. If it comes into contact with bare skin, it must be washed off immediately, as other methods such as using nail polish remover or sandpaper will not be effective.
Overall, POR-15 Fuel Tank Sealer is a safe and effective product for restoring and sealing fuel tanks, provided that the necessary safety precautions and application instructions are followed.

Preparation and cleaning
Drain and Remove:
Firstly, drain all fuel from the tank. It is crucial to ensure the tank is entirely empty before proceeding. Then, remove the tank from the vehicle. This step provides access to the tank and makes it easier to handle during the cleaning and sealing process.
Cleaning:
The cleaning process involves multiple steps to ensure the tank is free from any contaminants. Start by using a cleaner degreaser, such as the POR-15 Cleaner Degreaser, to remove any fuel varnish, gum, sludge, or other coatings from the inside of the tank. Mix one quart of the cleaner degreaser with one quart of hot water, and slosh it around inside the tank. Leave the tank in various positions to ensure the cleaner reaches all surfaces.
Next, use a rust remover and metal prep solution, like the POR-15 Metal Prep, to neutralize and remove any surface rust. This step also etches the metal, creating a better surface for the sealer to adhere to, and adjusts the pH of the surface. Follow the instructions on the product, allowing adequate time for the solution to work effectively.
After the cleaning process, rinse the tank thoroughly with water and ensure it is completely dry before proceeding to the sealing stage.
Surface Preparation:
Before applying the sealer, ensure the tank is free of any plastic parts. The tank must be entirely metal for the sealer to adhere correctly. Cover the outside of the tank with painter's tape and plastic to protect it from accidental sealer contact. It is also important to wear gloves during the sealing process to protect your hands.
By following these preparation and cleaning steps, you will ensure that the POR 15 fuel tank sealer adheres correctly, providing a strong and durable seal that is impervious to fuels and additives.
