Hello, I have a 135 Gallons aluminum fuel tank in my boat that cannot be removed from its location. How many quarts of sealant do you recommend and how to apply it all inside as the tank cannot be moved and rolled... With a paint roller ?

Asked by: Johnny Cash
Unfortunately we can not recommend the gas tank sealer products for this application. The items that we offer require you to remove the tank to rotate it and fully coat the inside for a complete seal. We apologize for the inconvenience.

Now I understand that the petcock must be covered from the outside to keep the solution from leaking out. My question is will the solution end up plugging up the hole from inside that's meant for the petcock?
