What material can be used for potting pickups?
Most industrial waxes should be used and often, specific epoxy potting solutions are used for permanent bonding of pickup components such as circuit boards, to hide design layout and to keep the pickup from being modified. There are also specific potting varnishes of different grades and some need to be oven heated to cure the materials. You need a material that will keep minute spaces between the ferrous and magnet materials from vibrating that can cause microphonics.
