I don't have a catalog anymore, but Vector used to make a variety of
pins, for both wire wrap and solder, that fit in their perfboards.
Punch in the pins, mount the components on them, run the connections
on the bottom and solder. They also had a wiring pencil that could be
used to run the connections. The wire had an insulation that would
melt when hit with solder. I wired up a couple of simple IC based
digital designs with one. I just used normal DIP sockets for the IC's.

Vector Electronics has a website with catalog information on it.

The wire you are mentioning is like "SolderEze" or some name
similar to that, usually found in #26 AWG size. I've used it but
would just as soon go with ordinary Kynar insultaion wire-wrap
stuff. SolderEze tended to get abrasion of the insulation, resulting
in cross-circuiting. Especially so with heat.

I got spoiled with #24 and #26 Teflon insulated solid wire, strips
easily and never abrades the insultation.
