Renew old tanks in cars, trucks or motorcycles using Eastwood's Gas Tank Sealer.
Gas Tank Sealer should not be applied if you use fuels containing more than 10% ethanol, as this can degrade the sealer. Please contact our experts if you have questions about whether this sealer is right for your tank.
Instead of searching everywhere for a hard-to-find tank, use Eastwood fuel tank sealer. One pint of sealer treats tanks up to 12 gallons capacity. This is the same sealer found in the Eastwood Gas Tank Sealer Kit for Automobiles; order these bottles if you have a larger tank, already own the needed prep supplies or want to seal a freshly-built custom tank. Visit the Eastwood Garage for a full tutorial on How to Seal & Restore a Gas Tank or contact our DIY experts for more information.
How to determine if Gas Tank Sealer can be used on a Fiberglass Tank.
Some earlier FiberglasTanks (generally pre mid-1980s) did not have a complete gel coat on the inside of the tank. Without this gel coat, the Gas Tank Sealer and the required cleaning would potentially soften and degrade the fiberglass tank.
Newer tanks ( since mid-1980’s) fiberglass tanks typically do not have this issue because they have a gel coating inside. To confirm if your fiberglass tank is compatible with the Gas Tank Sealer, look inside tank with flashlight. If the inside of the tank is smooth, the sealer should be fine to use. If they can see strands or the actual fiberglass matt, then you are not able to use the Gas Tank Sealer.
