The sealing is like clear coating a bare steel frame. If there is no rust when you clear coat it, then it will/should not rust after. If your rust is in the filler neck that is attached to the body then you could have the filler neck only coated on the inside. If there is rust inside the tank then you could have that coated. The coating is normally for steel tanks not stainless, but it couldn't hurt. If your tank or filler neck is made from 304 stainless, it will rust eventually. If you want something that is very rust resistant it should be made from 316 stainless. I am thinking about building an aluminum tank for my Cobra. It will be sealed on the inside along with the filler neck.

Good luck,Terry
