I found that beeswax never corroded any metal, but I must confess
that if a project was deemed to need total encasement then I would
spray it with conformal coating first. Without encasement in
beeswax the marine environment was lethal on the slightest or
smallest uncoated surface, give it a scratch to work with and in no
time at all that salt water had eaten its way through half the circuit.
