I "painted" the bottom 3" of my new (2 years ago) steel tanks with West System epoxy. Let's see how they hold up.
But yes, corrosion of the steel ones is a big problem. My old ones that came with the boat looked OK, until I removed the tanks.... the bottom 3" of tank stayed in place, while the top 9" of tank came out! Rusted completely through.
I think the problem is, on a port tack, the bottom of the tanks is in salt water if you bury the rail.
