What kind of oil tank?  If it's for crude oil it will probably be full of
natural gas fumes so you'll have to flush it out well before welding.

JB Weld it and forget about it.
Sometimes the easy way is the best.

Then I thought about soldering up he
holes, sort of like a radiator repair.  Would this be a better sol'n than
welding?  I suppose if there are large areas of rust in there, I may be
better off cutting the section out and welding in a patch panel.  If
soldering is the way to go, where could I find the solder/flux (silver?),
and would one of those small propane torches be enough (that's what I've
got, no access to an  oxy/act rig).

If the steel is rusted and caused the pinholes, you can
never stop the rust and the solder will be a very temporary
fix.

The only proper way to fix the tank is cut out the rusty 
metal (where it is thin, of course) and then weld in
a replacement section.  While you have the tank open,
clean out as much rust as possible.

*******  Don't cut the tank open with anything that causes
sparks unless you fill the tank with Nitrogen (or water),
whatever is appropriate for your cutting tool.

Then, after you have repaired the tank, put in a dilute
mixture of metal prep (Phosphoric acid) and let it kill
the rest of the rust.  Then, after drying the tank, coat
the inside with an appropriate coating.  It might be that
the gasoline tank coatings may be of use here.

The tank will outlast the rest of the hardware when you
get done and it will not leak again.
