POR15 Fuel Tank Sealer Prevents Rust and Leaks Effectively

Imagine your vehicle stranded due to a rusted, leaking fuel tank—not only disrupting travel plans but posing serious safety risks. A corroded tank acts like a ticking time bomb, ready to leave you stranded. POR-15’s Fuel Tank Sealer offers a comprehensive solution to these problems, providing durable protection for your vehicle’s fuel system.

Designed specifically for metal fuel tanks, POR-15’s high-tech sealer resists degradation from various fuels, including diesel, DEF additives, E10 ethanol, and high-alcohol blends. Its silver formulation combines exceptional strength with superior fuel resistance, ensuring long-lasting protection.

Key Benefits of POR-15 Fuel Tank Sealer

• Complete Leak Prevention: Acts as an internal liner, sealing minor leaks and preventing rust and corrosion.
• Broad Fuel Compatibility: Works with all common fuel types, eliminating concerns about chemical degradation.
• Easy Application, Long-Lasting Results: Simple steps deliver durable protection with minimal effort.

Preparation Steps for Optimal Results

Proper preparation is critical for effective sealing. Follow these steps before application:

1. Inspect the Tank

Ensure the tank has no plastic components and is structurally sound. Plastic parts must be removed, as the sealer adheres poorly to non-metal surfaces.

2. Thorough Cleaning

Use POR-15’s Cleaner Degreaser to remove loose rust, old sealant, and contaminants. This ensures maximum adhesion between the sealer and metal surfaces.

3. Surface Treatment

Apply POR-15’s Metal Prep to etch the interior, eliminate residual rust, and create a zinc phosphate layer. This enhances the sealer’s bond and longevity.

Application Guide

1. Degrease the Tank

   Mix 1 quart of POR-15 Cleaner Degreaser with 1 quart of hot water. Pour into the tank, agitate thoroughly, and let it sit to dissolve deposits. Rinse until no residue remains.

2. Acid Etching

   Pour Metal Prep into the tank, ensuring full coverage. This dissolves rust and forms a zinc phosphate coating. Drain after the recommended time.

3. Drying

   Ensure the tank is completely dry using compressed air or natural evaporation. Moisture compromises adhesion.

4. Apply the Sealer

   Pour the sealer into the tank, rotating to coat all surfaces evenly. Use a brush for hard-to-reach areas. Avoid excessive agitation to prevent bubbles.

5. Drain Excess

   Invert the tank for one hour to drain surplus sealer. Collect runoff for reuse or proper disposal.

6. Curing

   Allow 24–48 hours for the sealer to harden in a ventilated area. Avoid disturbance during this period.

7. Maintenance

   Add fuel stabilizer during refueling to prevent ethanol-related moisture absorption and corrosion.
