Not sure if it is the same stuff, but back along at work we used to have a product that was a water displacing agent, it came in a spray can, you simply sprayed the boards and switches etc and it resisted water ingress and displaced any water currently on teh units. Would love some of that...are we talking the same thing here?? if so, recalling how good it was, its all youll need.
Did a search...............................This is good stuff,

Its sold here for bikes, but it leaves a non greasy residue, perfect for the iside of your tank on the motors and boards, non conductive and gets rid of moisture there already. Worth a couple quid and one application will last around 12 months, I got some just to preserve the internals anyway.
Just anothe ridea
