Flex Seal will not work on a gas tank. The product is designed for use on leaks in pipes, hoses and roofs. It will not adhere to metal or plastic, and it will not stop a leak in a gas tank.
If you’re looking for a way to seal up a gas tank, you might be wondering if Flex Seal will work. The short answer is yes, Flex Seal can be used on gas tanks. However, there are a few things you need to keep in mind before using it.
First, make sure the surface of the gas tank is clean and dry before applying Flex Seal. If there’s any dirt or grime on the surface, it could prevent the sealant from properly bonding.
Second, you’ll want to apply a thick layer of Flex Seal to the surface of the gas tank.
This will help ensure that there are no leaks.
Third, allow the Flex Seal to cure for 24 hours before putting anything in the gas tank. This will give the sealant time to fully set and harden.
Overall, using Flex Seal on a gas tank is a great way to prevent leaks and keep your fuel where it belongs – in the tank!
How to Seal a Metal Gas Tank
Are you looking to seal a metal gas tank? Whether you are trying to preserve an old classic car or motorcycle, or you are wanting to keep your fuel fresh for your lawnmower, there are a few things you can do to ensure a good seal.
The first step is to clean the tank thoroughly.
Any dirt, rust, or other debris will only create more problems down the road. Once the tank is clean, it needs to be dried completely. This can be done with a towel or compressed air.
If using compressed air, be sure not go too crazy and dent the tank.
Once the tank is clean and dry, it’s time for sealing. There are various products on the market that can be used for this purpose.
The important thing is that it seals well and won’t react with the metals in your gas tank (which could lead to further corrosion). A good quality sealer will also resist fuel vapors and chemicals. We suggest something like POR-15 Fuel Tank Sealer .
This product comes highly recommended by many restorers and mechanics alike.
To apply, start by mixing up a small amount of sealer according to instructions. Then use a brush or roller to apply an even coat inside the gas tank.
Be sure to get all areas well coated – top, bottom, sides, corners, etc. Once applied, let the sealer cure according to instructions (usually 24 hours). After it has cured properly, you’re ready to add fresh gasoline and hit the road!

Will Flex Seal Hold Gasoline?
No, Flex Seal will not hold gasoline. While Flex Seal is an excellent product for sealing up cracks and leaks, it is not designed to hold gasoline. Gasoline is a highly flammable liquid, and if Flex Seal were to come into contact with a spark or flame, it could cause a serious fire.
If you need to seal a leak in a gas tank or fuel line, we recommend using a product that is specifically designed for that purpose.
What Can I Use to Seal a Gas Tank Leak?
There are a few things you can use to seal a gas tank leak, but the most effective and permanent solution is to weld the tank. This will require special equipment and training, so it’s not something the average person can do at home. If you’re not able to weld the tank yourself, you can take it to a professional welder or mechanic.
Another option is to use an epoxy resin or sealant specifically designed for sealing gas tanks. This isn’t as permanent as welding, but it will provide a temporary fix until you’re able to have the tank professionally repaired.
Can Flex Seal Fix Gas Leaks?
No, Flex Seal cannot fix gas leaks. While it may be able to temporarily seal the leak, it is not a permanent solution and gas will eventually seep through. If you have a gas leak, it is best to call a professional to fix it.
What Will Flex Seal Not Stick To?
There are many things that Flex Seal will not stick to including: -Porous surfaces such as wood, paper or fabric -Oily, greasy or dirty surfaces
