Grounding pole pieces; Better conducting adhesive shielding?

    While I've grounded pole pieces successfully on other pickups before with no problem, for whatever reason the conductive adhesive on the roll of StewMac tape I currently have won't work with either my Lollar J's or P pole pieces.

    I've cleaned the surface of the magnets with alcohol & naptha and I've burnished the living heck out of the tape but when I check for continuity with my multi-meter it's a no go. Occasionally I can get a one or two pole pieces to ground d but never all of them. The StewMac tape does have continuity when I tape it to itself shielding control cavities.

    Is there a better conductive adhesive shielding than the StewMac? Do I have a bad roll or does anyone have any other tips? I can't recall where I got the shielding I used in the past but had no issues making that work.

    I've run into this, too, and believe the pole pieces are coated with a non-conducting corrosion inhibitor.

    Thanks for response, I was wondering about that very same thing. I've found some work arounds like sticking a thin strip of the non adhesive side facing up, in contact with the magnets and holding it in place with some more copper shielding but after a few years the adhesive seems to dry out and it works loose.
