Coax seal is a poor product for sealing coax connections.  It's sticky 
and leaves a nasty residue if you ever have to take the connection 
apart.  I really dislike ever using it.  A MUCH better way to do it is 
to use self fusing rubber splicing tape and good quality Scotch Super 
33+ electrical tape.  Speaking of electrical tape.....NEVER stretch it 
when applying and use a scissors or knife to cut it.

Dx-Engineering has an excellent document on how to use these products.  See:

Incidentally, DX-Engineering sells these products but they are also 
available locally at any good electrical supply store or maybe one of 
the big-box stores if you're lucky.
