I once read by someone else (can't claim this as my own) a method for
Coax-seal that captures all the benefits of Coax-seal with none of the
drawbacks: a layer of electrical tape, a layer of Coax-seal and a layer of
The first layer of electrical tape means the whole mess comes off as cleanly
as if it were just electrical tape.
Truth be told, however, lately, I've been using electrical tape sprayed with
a urethane (varathane, etc.) sealant covered again with electrical tape.
Just had to replace a connection done in that way and the connections
underneath looked brand new.
I've even successfully used that method to protect pigtail connections,
which as most of you know are very problematic because of the wicking action
of coax braid.
