“Finished my fuel tank this past weekend and all went well. I had first started with cleaning the tank and welding a few holes up in my 44 gallon aluminum tank. I do have to say that this all took a matter of weeks to complete because of proper drying and work schedule. The process was very straight forward. I couldn't believe how well the Gold Standard coated the inside of the tank with multiple baffles in the tank. I then painted the exterior with gloss black. This being in the hull of my boat never to be seen by sun again but it sure looks good. Thanks for such a great product!" -Glenn B. RustSeal Tank Sealer

I have a larger hole, about 3/8th of an inch in diameter. The gas tank is still on the car, and I'm hoping you have a product that I can use to seal it? I sure hope so. Please let me know as soon as practical, as I need the car - it's my only one.

I want to protect the weld seams in my fuel tank from rust. Can the rust sealer be used internally on a tank? If not, can the tank sealer be painted on the seals inside the tank instead of lining the entire tank? A family member keeps discouraging me from DIY fuel sealers as he had a friend that used one and came apart clogging the fuel system. Both these guys are mechanical engineers that work in Aerospace... so it's hard to discount their advice. What advice can you give for my application and perhaps this family member?
