This makes me ask, Why remove the goo?  Little will stay on the coax jacket 
and what does stay on the connectors doesn't hurt the reusability. On 
occasion it leaves the connectors looking a bit scruffy, but more often than 
not, most comes right off.

IF shiny connectors are the criteria, just carefully rub a bit of "pledge" 
or car wax on the connectors before applying the heat shrink with the 
flooding compound. Just don't get the wax on the coax jacket, or more than a 
film on the connectors. A tiny amount of DC-4 (flooding compound) will keep 
virtually anything from sticking. Be careful not to get the wax or DC-4 on 
your hands and then touch the coax jacket where you plan on sealing it.
