Both were used in a number of places including coil forms and wiring.
I used varnish to hold coils in place (as mentioned in the initial
post) but not to coat them.  On the other hand, the wire used was
bare, enameled magnet wire or DCC enameled wire (and in more than one
case, Litz wire) which ever I had on hand at the time.  The coatings
didn't seem to make a lot of difference nor did sealing some of them -
notably chokes - in wax afterward.  I used Q dope but not all the
time.  It was a "special cases" material used when nothing else would
do.  I can't remember the criteria that had to be met before I got out
my little bottle but apparently they were strict.  :-)

In reading and participating in this thread as well as the parallel
ones and the one on the old caps, I'm finding long forgotten memories
coming back - some of the rare good ones from a childhood & teenhood
that was far from good by any definition of the term.  (That gets into
areas that I'd really rather not discuss on an open forum.)  The fact
that some involve letting smoke out of places that smoke aughta not be
let out doesn't make them any less good.  Smelly, though. Definitely
smelly.

No matter what else happened, though, those memories could not be
taken from me and now they're coming back - smells and all - and I'm
finding a lot of comfort in them.  Considering what else is happening
in my life (specifically with Noelle), that comfort is more than
welcome.

Carl mentioned how interesting it is how our minds work that we can
easily shift from automatic everything rigs to using something
originally made before some of us were born.  I find it interesting
what we sometimes find as comforting.  I don't drink except the
occasional bit of Jameson's in my coffee (occasional: the fifth I
bought New Year's Eve is still in play.) so this seems to be my
substitute.  :-)
