@keloooe: I found the adhesive was conductive. Tested from opposite sides of the cavity, with several joins, and it read a few ohms.
I thought of it after reading Gavin Turner's post where he tested it: http://guitarkitbuilder.blogspot.com...for-slugs.html

But I'm not selling the stuff... was just mentioning it as it is a convenient replacement if you forget to order the tape with your guitar
