Red-Kote Fuel Tank Liner is an internal fuel tank liner designed to seal leaks and prevent further rusting. It is a solvent-based polymer coating that is resistant to gasoline, diesel fuel, alcohol, and other fuel additives. It is important to note that Red-Kote is not suitable for all types of fuel tanks and fuels.
Red-Kote is not suitable for tanks larger than 50 gallons. This restriction is due to the product's limitations in terms of coverage and drying time. Red-Kote is sold in one-quart cans, which are typically enough to seal two tanks. However, it is important to consider the size of the tanks being sealed, as using Red-Kote on larger tanks may result in inadequate coverage.
Additionally, Red-Kote should not be used with biodiesel fuel. Biodiesel fuel, also known as biofuel, is a type of fuel that is made from renewable sources, such as vegetable oils, animal fats, or recycled cooking grease. While biodiesel fuel has environmental benefits, it is not compatible with all fuel tank liners and sealants. Red-Kote, in particular, is not designed to withstand the unique chemical properties of biodiesel fuel.
Using Red-Kote with biodiesel fuel can lead to several issues. Firstly, it may not effectively seal leaks or protect against rust, which are its intended functions. The chemical composition of biodiesel fuel can react differently with the Red-Kote liner, potentially causing it to break down or fail prematurely. Additionally, using Red-Kote with biodiesel fuel may void any warranties or guarantees provided by the manufacturer, as it is specifically designed for use with gasoline or diesel fuel.
It is crucial to follow the manufacturer's instructions and guidelines when using Red-Kote or any other fuel tank liner. Improper use of these products can lead to safety hazards, damage to the fuel system, and voided warranties. Always refer to the product's specifications and seek guidance from a professional or the manufacturer if you have any doubts or questions regarding its suitability for your specific application.

It takes approximately eight hours to dry
The drying time of Red-Kote Fuel Tank Liner is an important consideration when using this product. It is essential to allow the liner sufficient time to dry properly to ensure its effectiveness and avoid any issues. On average, Red-Kote takes approximately eight hours to dry. This drying time is standard across different applications, whether it's for a motorcycle fuel tank or any other metal fuel container.
The eight-hour drying period is crucial for the formation of Red-Kote's unique membrane. During this time, the product cures and creates a tough, flexible, and seamless barrier. This membrane is designed to be durable and resistant to cracking or flaking, which are common issues with other fuel tank liners. By allowing the full eight hours, you can be confident that the Red-Kote has formed a robust seal, preventing leaks and protecting your fuel tank from further rust and corrosion.
The drying time of Red-Kote is also influenced by its solvent-based polymer coating formulation. This coating is designed to be resistant to various fuels, including gasoline, diesel, and alcohol, as well as other fuel additives. The solvent-based nature of the product ensures that it can effectively fill and seal pinholes and small leaks in the fuel tank, creating a smooth and intact interior surface. Therefore, the eight-hour drying period is essential to allow this solvent-based polymer coating to cure fully and provide the best possible protection for your fuel tank.
It's important to note that the drying time may be affected by environmental conditions, such as temperature and humidity. In ideal conditions, the eight-hour timeframe should be sufficient. However, if the temperature is too low or the humidity is high, it may take slightly longer for the Red-Kote to dry completely. Therefore, it is recommended to apply Red-Kote in a well-ventilated area with moderate temperatures and low humidity to optimize the drying process and ensure the best results.
To ensure the effectiveness of Red-Kote, it is crucial to follow the manufacturer's instructions and allow adequate drying time. While the product is designed to be flexible and resistant to cracking, improper drying or impatience during the process may compromise its integrity.
