I have tried contact glue, but the insulation is insufficient. It leaves
many voids. I need something that doesn't leave any significant void,
if carefully applied. A potting compound of some sort, or maybe a resin
of those that cure with ultraviolet light (i read of people making
electrets with these resins, so the insulation is good).
