David,

I beg to disagree, some time ago I used some of the 'vinegar' stuff on a
splice with insulated copper wire (#14 THHN) - and I can say that the bad
stuff keeps creeping for a long way.  After a couple years, I had occasion
to examine it and found the stuff had crept up under the insulation and
caused corrosion as much as 6 inches from the point where it was applied -
It did make a good weather seal, but at the cost of electrical properties
loss.  Fortunately, this was not in any critical application.

No longer will I use commonly available RTV direcly in electronics
applications - even the consumer grade 'non-corrosive' RTV commonly
available that I bought recently had a vinegar smell to it.

73,
