Altho, these may be easier to use than dux seal,
beware- if the stuff smells like Vinagar (as in
Ascetic acid) , you may be contaminateing your
coax, as is my understanding. And, MOST RTV's
have this feature (contaminateing your coax)!
Not a good situation! as info, Jim NN7K

Not usually a problem when going through a wall unless the outer insulation
is broken, but RTV is not may favorite for this. Plain old caulk works great
unless you have a big void to fill.

Jimmie already go this one, but if the seal is pretty much out in the
open it will not contaminate the coax jacket. Normally the stuff
won't bother the jacket any way, just don't apply directly to copper
or aluminum braid as the Copper will turn green.

OTOH there are versions available in Silicon that are
non-contaminating and there are also latex/water based versions. Most
of the DAP (TM) ( made by DC) is water based although you can specify
Silicon. Once cured there is not a great deal of difference although
there are some.
