ISOPON Leak Stop is a specialized, high-performance 2K polyester bridging compound specifically engineered for the permanent repair of leaking fuel tanks, radiators, and sumps. Infused with a high concentration of structural fibers and aluminum particles, it provides a metallic-strength seal that is resistant to gasoline, diesel, oil, and water. Its dark grey finish allows for a professional, inconspicuous repair on metal surfaces.

Key Performance Features:

Fuel & Oil Resistant: Formulated with a specific resin system that does not dissolve or soften when in contact with hydrocarbons, making it the industry standard for emergency and permanent tank repairs.
Fiber-Reinforced Strength: Contains structural fibers that "bridge" holes and cracks, providing a rigid, high-pressure seal that resists the vibrations and thermal expansion of a running engine.
Pressure Capable: Once fully cured, the compound can withstand the internal pressures typically found in automotive cooling systems and fuel tanks.
Excellent Adhesion: Bonds aggressively to bare steel, aluminum, galvanized steel, and GRP/Fiberglass, even in challenging environments.
Rapid Emergency Repair: Cures to a rock-hard finish in under 20 minutes, allowing for fast "get-me-home" or permanent shop repairs.

Expert Tip: For larger holes or high-pressure radiator leaks, you can use the "sandwich" method: apply a layer of Leak Stop, press a small piece of fiberglass mesh into the wet compound, and immediately apply a second layer over the top. This creates an incredibly strong, reinforced patch.

Safety Warning: Contains Styrene. Highly flammable. Always use in a well-ventilated area. Wear nitrile gloves and eye protection. Do not use on plastic fuel tanks (polyethylene) as polyester resins generally do not bond to these materials.
