Resealing a galvanized tank after modification?

[Rhino]

I have a standard galvanized steel tank that I've retrofit a newer fuel module into. When I began the process I wasn't really thinking about the possibility of rust. It seems that typical sealants are frowned upon due to breakdown over time. I'm contemplating regalvanizing and will make a few calls tomorrow. Is there any other process/product I should consider?



Thanks!

So far I haven't been able to locate a shop who would one-off regalvanize a tank. They're all wanting large tonnage. Radiator shops want to coat the tank, however no one has a warm fuzzy any time I mention ethanol. Given the lack of quality, higher octane, 100% gas at the pump I don't feel comfortable if they're not completely behind it.

It looks like I'll be sealing it myself, however I need to find the proper product. I've completely taken Eastwood out of the mix due to their lack of chemical resistance. Por-15 and Red-Kote appear to be the most spoken of brands on the web, however each talk about the other gumming up in different scenarios and try to prove their superior methodology. Has anyone used one of these (or other) products in the past?
