There is a product that is suppose to recondition gas tanks.  It's brand
name is KREEM.  It requires a two step process on step is using 
KREEM Tank Prep which "removes oil and grease, disolves rust and etches
the metal prepareing the metal gas tank for KREEM GAS TANK SEALER.  This
is suppose to coat the tank inside sealing leaks and covering up rust.
It contains a rust inhibitor.  The product can be ordered from Dennis Kirk
(800-328-9280).  I have never used this product, however using an acid to
clean the inside of tank or to remove corrosion would be the last step I 
would take.
