The first is RTV GE part number 142. The part number is critical!! It is
a non acidic RTV. If you use an acidic one it will destroy the coax
shield in about 3 weeks. If the RTV smells slightly like a citrus fruit
DO NOT USE! This is the acid based kind.
Second is liquid electrical tape. It comes in quite a few colors. About
$5.00 for a 6 oz. can. Can is similar to a PVC cement can. Stuff dries
in about 20 minutes and is great for covering entire connector. Can be
found at good marine supply houses or a larger ACE hardware stores.
