Permatex Gas Tank & Radiator Repair Kit is designed to seal small holes and weak seams in gas tanks without the need for welding or tank removal. It effectively repairs leaks and holes in all types of radiators, providing a reliable solution for maintenance and restoration. The non-shrinking formulation is resistant to ethanol, a longer working time, and remains flexible after curing. Once fully cured, the repair material can be machined, tapped, drilled, or filed for a precise finish. It hardens in just 60 minutes and dries to a brown color, making it both durable and easy to use. Model Number: 84334
