Permatex Fuel Tank and Radiator Repair Kit
The Permatex Fuel Tank and Radiator Repair Kit is a two-component stick that can seal holes, seams, or cracks in metal tanks, radiators, or gas cans. It is designed to be kneaded together and provides excellent chemical and moisture resistance and is non-flammable. The repair resin is designed to cure within two hours at temperatures between 50°F and 75°F (10°C to 25°C). Repairs made at lower temperatures will take longer to cure.
The Permatex kit includes easy-to-follow instructions with photographs, making it simple for anyone to use. It is important to read all directions before beginning the repair process. The first step is to remove the gas cap to vent the tank and ensure adequate ventilation. If the leak is large, the tank should be drained or the liquid level reduced to at least 2 inches below the damaged area. The damaged area should then be prepared by removing any oil, grease, tar, or dirt.
The Permatex Fuel Tank and Radiator Repair Kit is not recommended for use on plastic gas tanks. For plastic tanks, Permatex offers a separate Plastic Tank Repair Kit. This kit is designed to repair cracks up to 4 inches in length and holes up to 3/8 inch in diameter.

While the Permatex Fuel Tank and Radiator Repair Kit has received some positive reviews for its effectiveness and ease of use, there are also reviews that indicate it may not work for all situations. Some users have reported that it did not work on plastic radiators or that the repairs did not last long-term. It is important to carefully follow the instructions and ensure that the kit is suitable for the specific type of repair before use.
