It certainly is messy and I used to believe in "proper waterproofing" of
connectors until mother nature proved to me there is no such thing or at
least none that is permanent or guranteed.

Becasue that is what it's designed for. It does not hinder the metal to
metal contact, but it does serve as an insulator and water stop where it's
supposed to do so.

Messy it is and you might as well pitch any connector that gets dropped.
I quit using the stuff due to the mess, but it was designed to make the
government happy doing what it does best.

You don't wear gloves when working with that stuff.. That's like trying to
doing PC board work while wearing gloves.

I used to believe that to until nature used a stroke of lightning to remove
every bit of water proofing off every connector at the top of the tower.
(Removed the silver plating too) A bit later (few minutes) I had water
running out of one of the rigs onto the desk which is what I get for using
9913. I gave away close to 800 feet of the stuff and hauled over 200 feet
out to the road (all still in good shape). I gave away the last couple
hundred feet Saturday. I went to LMR-400 and am now upgrading to LMR-600 for
everything including runs over a 100 feet on HF.
