My Buying Guides on Red Kote Tank Sealer
When I first decided to protect my fuel tank from rust and corrosion, I came across Red Kote Tank Sealer. After using it and researching thoroughly, I want to share my experience and tips to help you make an informed choice.
What is Red Kote Tank Sealer?
Red Kote is a specialized coating designed to seal and protect metal fuel tanks from rust and leaks. It bonds to the inside surface of the tank, creating a durable barrier that prevents corrosion and fuel contamination. From my experience, it’s ideal for restoring old or damaged tanks without the need for costly replacements.
Why I Chose Red Kote
I chose Red Kote because it’s widely recommended by professionals and DIY enthusiasts alike. It’s known for its ease of application, strong adhesion, and resistance to gasoline and ethanol blends. Plus, it dries relatively quickly, allowing me to get my project done without long delays.
Key Features to Look For
- Compatibility: Ensure the sealer is compatible with the type of fuel your tank will hold (gasoline, diesel, ethanol blends). Red Kote works well with most fuel types.
- Durability: I wanted a product that offers long-lasting protection. Red Kote’s formulation resists cracking and peeling over time.
- Ease of Application: Red Kote comes in ready-to-mix kits, which made the application process straightforward for me. It requires some preparation but no special equipment.
- Drying Time: The faster the sealer cures, the sooner I could reassemble and use my tank. Red Kote typically cures within 24 hours under ideal conditions.
Steps I Followed to Apply Red Kote
- Clean the Tank Thoroughly: I removed all rust, old paint, and debris by sanding and washing the interior. A clean surface is crucial for adhesion.
- Dry the Tank Completely: Moisture can prevent proper curing, so I made sure the tank was bone dry.
- Mix the Sealer Properly: Following the instructions, I mixed the components evenly to activate the sealer.
- Coat the Interior: I poured the mixture inside and rotated the tank to coat every surface evenly. Some people prefer using brushes or spray, but I found rotation effective.
- Let it Cure: I allowed the tank to sit undisturbed for the recommended curing time before reassembly.
Things to Keep in Mind
- Always work in a well-ventilated area because the fumes can be strong.
- Wear protective gloves and a mask to avoid skin contact and inhalation.
- Follow the manufacturer’s instructions carefully for the best results.
- If your tank has severe rust or holes, sealing alone might not be enough; consider repairs first.

I found it available online through various automotive suppliers and marketplaces. Local auto parts stores may also stock it. Compare prices and check for kits that include all necessary components.
