Treating cable terminations in wet environment

Paint completed connections with polyurethane or blob on some RTX silicone (as used in electronic applications; standard silicone attacks copper while curing.)

Thank you. I was actually planning on using silicon...

When I was dealing with boat wiring the stuff that seemed to work best is this: Boeshield T-9. It puts a pretty substanial film over the connection and penetrates very well. If the termination is completely exposed the silicone should work very well but if you need to make sure every little crevice is protected the Boeshield is good stuff. Click on the image of the big container to get a detailed sales pitch.

This is really good. It feels great to start at the right place when seeking help. Again, thank you. Audiogon rules!

Something that is very effective and works great as well is simple candle wax. Take a thin lit candle and carefully drip the hot wax on the connection. I use this on my outdoor speakers every year and it works like a champ..
