Sorry, I wasn't clear. I'm used to talking to manufacturing types and we speak the same language...sometimes without talking.
Use the tape or saran as a surface to make a fairly smooth, yet thin, cured adhesive area with the wire embedded. Then remove the tape or saran and install the new grips with minimal growth of the bar end. If the they stick, then it is stuck and has done its job and likely won't go anywhere and the grip adhesive should work equally well. You can test for adhesion removal before the actual article as well if you'd like to know beforehand. The new coated non-stick Reynolds foil might do the same job.
God bless America!
