I've had pretty good luck with a POR-15 tank treatment.

Three step POR-15 process:

1) Soak and rinse with lye to get out the hydrocarbon glop.

2) Fill with phosphoric acid solution and something like sheet
metal screws to knock off rust and loose liner. Soak, shake,
repeat as ambition dictates then drain and rinse.

3) POR-15 liner. Slosh around in tank, let sit for a while, then
drain.

The kit comes with better directions. This is from memory.
Watch out not to expose paint that you care about to the
various chemicals. Definitely remove the petcock(s) before
starting. Watch out for POR-15 and aluminum. (seems to
attack it).

POR-15 is supposed to work better than Kreme. There are
other treatments around too. I suspect the preparation part
would be the same for all.

If you don't fancy DIY there's a chap that advertises in the VJMC
Autojumble mag that can apparently return the inside of the tank to
shiny bright metal again, I'll dig out his number if anybody wants it.

Among the "miraculous" products, there is also french one called Restom.
Comes in kits, with one washing solution, to remove the dirt and rust,
and one coating resin, that takes some time to dry (because ventilation
is poor).
