Tank doesn't have baffle.am I doing anything wrong. Thanks

POR15 does not stick to clean steel! It does stick well to non scale based rusted steel. POR 15 Gas tank sealer would be a good choice. I would sand blast the outside bottom and apply fuel rated epoxy and glass fiber over the whole bottom to assure there is material that can continue to serve. There may be many other places just waiting to fail on that surface. Jim

If you are talking about the POR15 fuel tank sealer product, follow the instructions.
