Mike,
I've had excellent long term success with Ham-IV style rotors by replacing the
stock terminal strip screws with stainless screws. I've never waterproofed the
connections.
I've never had a moisture related failure of the connections after over 20
years of using this technique on multiple Ham-IV style rotors.
73!
