Every year I have a hard time removing the old zincs from my Side Power thrusters. A little difficult to see in the photos but there is a lot of "white powder" on the inside of the zinc where it fits over the nut that holds the props on. It takes quite a bit of tapping and wiggling with Vice Grips to get them off.
Is there a grease that won't interfere with the conductivity between the zinc and nut? Can I use some type of Anti-Sieze? If so, what formula?
