Summary: 


I'll pass on a tip I learned from people who restore old cars. To
remove rust use a product called "Navel Jelly". I suspect that the
active ingredient is oxalic acid (a weak acid about as dangerous as
lemon juice), but the stuff works. If you have a lot of rust (most old
cars do) add SMALL ball bearings or BB's to the jelly and shake gently.
After the final treatment the jelly will rinse off with water and leave
a surface which may be treated with one of the tank coatings.

If you should be so fortunate as to have access to a small cement
mixer, strap the tank (firmly) in the mixer with the jelly in it. You
may want to reposition the tank as few tumes, but it beats shaking the
tank for a hour or so. Don't use big breaings or shake hard, you can
dent the tank from the inside out, leaving dents that hardly show until
the next paint job looks like "orange peel".
