Karen,
 
My local office supply store orders the adhesive for me and has no problem
getting it.  It's not really a tape - its more like a rubber cement on a
backing paper.  The paper is removed after applying to the first sheet of
mylar.  I think the tape can even be ordered in different grades of
aggressiveness.
 
On the inside of the rolls I have on hand, is the marking "United Mfrs.
Supplies, Inc., Syosset, N.Y. 11791  Your one source for framing needs."  You
could try to find them direct, or you can order it from Ken Clark at Office
Products in Berlin, NH 603-752-6464.
 
I'm not sure how important it is to have the acid free adhesive, since the
map never really touches the tape/adhesive, and there is plenty of
ventilation, but I still take the extra precaution.
 
Oh, I should mention that the scraps of Mylar-D I usually have left over
after a sleeving/encapsulation project, make great book covers!
 
I've never heard of the glue gun adhesive thing, but it would seem the paper
backed adhesive is a much better solution.
 
Hope this helps.
 
Regards,
Kurt
