Why Red Kote Tank Sealer Is Necessary
From my experience, using Red Kote Tank Sealer is essential for protecting the inside of fuel tanks. Over time, tanks can develop rust and corrosion due to moisture and contaminants. This not only weakens the metal but can also cause leaks and fuel contamination. Applying Red Kote creates a strong, protective barrier that seals tiny cracks and prevents further rusting, extending the life of the tank significantly.
I’ve also found that Red Kote helps maintain fuel quality by stopping rust particles from mixing with the fuel. This means fewer clogs in fuel lines and filters, leading to smoother engine performance and less maintenance. In short, sealing my tank with Red Kote has saved me from costly repairs and downtime, making it a necessary step in tank maintenance.
My Buying Guides on Red Kote Tank Sealer
When I first decided to use a tank sealer for my motorcycle’s fuel tank, I quickly learned that choosing the right product is crucial. Red Kote Tank Sealer is a popular choice among riders and restorers, so I want to share my experience and tips to help you make the best decision.
What Is Red Kote Tank Sealer?
Red Kote is a specialized coating designed to seal rusty or leaking fuel tanks. It creates a protective, corrosion-resistant barrier inside the tank, preventing fuel leaks and stopping further rust damage. I found it especially useful when restoring older bikes or fixing tanks that had started to corrode from the inside out.
Why I Chose Red Kote Over Other Sealers
When comparing options, I looked for something reliable, easy to apply, and durable. Red Kote stood out because of its strong reputation for sealing even severe rust and its compatibility with gasoline and ethanol blends. It also hardens quickly and adheres well to metal surfaces, which gave me confidence in its long-term effectiveness.
Key Factors to Consider Before Buying
1. Tank Condition
Before applying Red Kote, I had to assess how rusty or damaged my tank was. If the rust was very severe or there were large holes, I needed to do some patching or welding first. Red Kote works best on tanks with surface rust or minor pitting.
2. Tank Size and Quantity Needed
Red Kote comes in different kit sizes, typically sized for small motorcycle tanks or larger car tanks. I measured my tank’s volume to ensure I bought enough sealer to coat all the interior surfaces thoroughly. It’s important not to skimp on quantity for full coverage.
3. Application Process
I appreciated that Red Kote’s application involves cleaning and drying the tank thoroughly, then pouring in the sealer and rotating the tank to coat every inch. The process is straightforward but requires patience and care to avoid missed spots or drips.
4. Drying and Curing Time
Red Kote usually cures in 24 to 48 hours. I planned my project timeline accordingly, making sure the tank could sit undisturbed during this period for the best results.
My Tips for Using Red Kote Tank Sealer
- Always remove all old fuel, rust flakes, and debris before starting. I used a combination of rust remover and thorough rinsing.
- Follow the instructions closely. Temperature and humidity can affect curing, so I applied Red Kote in a well-ventilated, dry space.
- Rotate the tank slowly and continuously during application to ensure an even coat.
- After curing, I inspected the interior with a flashlight to confirm full coverage.
Where to Buy and What to Expect Price-wise
I found Red Kote at motorcycle parts stores and online retailers. Prices vary depending on kit size, but it’s generally affordable considering the value it adds by saving a tank from replacement. Buying from reputable sellers also ensured I got a fresh, effective product.
Final Thoughts
Using Red Kote Tank Sealer was a rewarding part of my restoration project. It saved me time and money by sealing my tank professionally and extending its life. If you’re dealing with a rusty or leaking fuel tank, I highly recommend considering Red Kote—and just remember to prepare your tank carefully and follow the instructions for the best outcome.
