I used this to make TV antennas for my attic. The glue seems to hold up well to the sealed cardboard, but I've added a few lines of thermoplastic glue in strategic places just in case the embedded glue loses adhesion over time in this protected but harsh environment. Resistance tests showed the adhesive to be a good conductor, but for my application I felt I needed an even lower resistance. After a short swing with the x-fine sanding sponge, the rosin solder spread like a dream. Using a Weller 140W soldering gun the glue stayed in place at this point and the copper dispersed the heat so quickly that the cardboard didn't burn.
