and as others have probably pointed out stay away from the silicone rubber
caulks and glass sealants, those usually give off an acid while curing (the
vinegar smell) that can etch the connector, and they just don't stay very

Our local hardware store has (among others) a black GE silicone
sealant which is specifically labelled as being suitable for use on
metals, and to be noncorrosive. It contains no acetic acid. I've
used it on F connectors on my TV and satellite-dish wiring - it stood
up to sunlight for quite a few years, and when removed did not appear
to have corroded the brass at all.
