Sealing coax connectors

[Steve Lund]

What is the latest in sealing coax connectors?

I recently had to lengthen a run of coax on which I used Coax-Seal.  I put the
Coax-Seal directly on the connectors.  What a mess!!  Is there some easy 
method of removing this stuff?

Should I have taped the connectors first and then applied the Coax-Seal?

Has anyone tried Dow Corning RTV-732 or RTV-3145?  I believe that both are
non-corrosive.
