Potting "damps' the sympathetic vibrations of the coil wires. These vibrations are the primary cause of microphonics and squealing. This will not only greatly diminish feedback but will usually give a more solid sound to the pickup.

This technique works on Stratocaster and Telecaster type single coil pickups as well as Gibson style humbucker and P-90 pickups. There is no need to remove the covers of humbucking pickups to do this although cleanup is a bit of work.

Bass pickups can also benefit from potting
I use wax ( paraffin in this case) as it does not react with the insulation on the windings. although lacquer will work it may react with some of the different insulation materials that pickup wire (magnet wire) use
