I'm looking for an acid based solder paste for electrical soldering.

I don't know what you mean by "electrical soldering", but regardless,
DO NOT use acid core solder for electrical/electroinics soldering.
Use rosin core solder. You can still buy rolls of good 'ol 60/40
(tin/lead) rosin core, the most common still-contains-lead type of
electrical solder, at any Radio Shack. If you need a more specialized
solder for special applications, yer gonna hafta do some homework.

If you are thinking to soldering large gauge (16g or larger) wires to
something like automotive connectors, you may want to reconsider.
Might be OK to merely "tin" stranded wire, but most modern connectors
are designed to worked better w/o soldering.
