RE: aluminum tape adhesive conductivity

There was a thread on this topic about a month ago.  The adhesive is not at
all conductive.  The edges of overlapping segments may or may not touch and
make contact, but there is speculation that the typically large amount of
overlap may offer capacitive coupling, especially in there is a continuous
corrugated Al duct inside.  Also speculation that small arcs will
essentially bridge any unconnected strips in operation.  I myself like to
play it safe and connect the strips with a piece of EMI gasket, as
illustrated on my web site:

I also just today received a flyer from The Electronic Goldmine,
www.goldmine-elec-dot-com, advertising some 1"W x 25ft L copper mesh tape for
$10, which boasts about a conductive adhesive, suggesting it can be used to
repair PC traces and attach to solar cell terminals.  Sounds like it would
be useful for running around the ID of a toroid to connect the aluminum
strips.  Plus you can solder to it!

Considering using aluminum tape to cover a toroid, is the adhesive
conductive enough so that the conductive surface is essentially
continuous?
