When I first started looking for a reliable tank sealer, I quickly realized how important it is to choose the right product. Red Kote Tank Sealer has a strong reputation, but to help you make an informed decision, I want to share my experience and what I learned along the way.
Why I Chose Red Kote Tank Sealer
I needed a tank sealer that could handle the tough conditions inside my fuel tank without breaking down or causing contamination. Red Kote stood out because it’s specifically designed for sealing steel and aluminum tanks, and it’s known for its durability and chemical resistance.
Key Features I Looked For
- Chemical Resistance: I wanted a sealer that could resist ethanol blends and other common fuel additives. Red Kote offers excellent protection against fuel corrosion.
- Easy Application: Since I planned to do the job myself, I needed something that wasn’t too complicated to apply. Red Kote’s brush-on or spray options made the process manageable.

- Non-Toxic and Safe: Because I handle fuel tanks often, I checked that the product was safe to use and didn’t emit harmful fumes once cured.
How I Prepared My Tank Before Applying Red Kote
Preparation is key. I thoroughly cleaned and dried my tank before application, removing all rust and debris. I followed the manufacturer’s instructions to the letter, which helped the sealer adhere properly and perform well.
Application Tips From My Experience
- Apply multiple thin coats rather than one thick coat to avoid runs and ensure even coverage.
- Allow sufficient drying time between coats; I waited about 30 minutes to an hour.
