Carl;  Just go to your home depot, and buy a roll of aluminum foil HVAC duct tape.  Even though the adhesive is not conductive, the width of the tape on either side of the seam serves as a nice low impedance capacitor, and the overall shielding effectiveness is nearly the same as if you were using copper foil tape with a conductive adhesive.  ( the kind with the little copper slivers in the glue)

I have used this and it actually works quite well, and have measured the emission results and seen it work. (20 yrs in EMC engineering)  Plus, the AL tape at HDepot is much cheaper and easier to obtain.
