Default Need some "waterproof" 12 v power connectors

Acetic acid corrosion has not been an issue on
any of the ones I have made up and/or repaired.


I have experienced Acetic acid corrosion in the past (didn't know what to
call it). I used liberal amount silicone on a VHF connector at the mast
head. 3 years later, when I pulled the mast, peeled off the silicone, the
metal connector were almost completely consumed by corrosion.

I suspect that the application was so heavy that the silicone compound
didn't have an opportuntiy to fully cure and the acid in contact with the
metal had a reaction with the metals of the connector..

It's been a few years but I seem to remember a strong acidic smell and the
surface of the remaining metal/mush was damp with this acid.

I stopped using silicone anywhere I would need a heavy buildup that might
trap or hold in the acid.

For electrical connection I stand by my earlier recommendations to purchase
the connectors that have a heavy adhesive shrink sleeving.. They are
expensive but for mast wiring the OP is only going to need a half dozen.
