[Elecraft] K3 near salt water

[Eric Swartz - WA6HHQ, Elecraft]

We do not recommend spraying corrosion-x inside the K3. That will void 
the warranty. Corrosion X is basically an oil based preservative, which 
will make a mess of the inside of the radio and also make it difficult 
to repair when needed.

In general, we have not seen serious interior corrosion on K3s in normal 
marine and tropical use where normal precautions are taken (keep the 
radio dry etc..) In those cases where the exterior screws did rust, the 
interior connectors etc. were free from corrosion. The exterior 
stainless screw kit for the K3 is the proper solution for this environment.

Is there anything I can,  or could have done differently to prevent the rust from developing?
