rusty tanks (was: Trojan)

[David Buchner <Buchner@wcta.net>]

When you say "soft" tanks, it gets me thinking of balloons or innertubes or
something, which makes me think of those bladders inside household
captive-air pressure tanks -- those households which have their own wells,
that is. Anyway, it's a steel tank with a heavy rubbery bag inside. I
haven't thought it out very far, so I don't know just how... but I'm
wondering if there's some way such a replaceable liner could be used to
deal with the rustiness in the dark insides of ballast tanks. By unscrewing
a small port at one end it was attached to, one could inspect or swap
liners as often as one liked. The tank itself could be pretty crude, but
the inside of the liner would be fresh and clean.
