I've used the stuff for quite a few years. and it's handled 
by most electrical supply houses. 

Now the question, WHY go to all the work of keeping the connectors 
shiny?  You can reuse them whether they have hot glue stuck to them of 
not. I don't reuse PL-259s, but pitch them anyway. The ones on the 
LMR-600 are expensive enough to save, but again, why care if they look 
pretty or not.   I want the tubing, tape, or what ever to seal tight on 
the connectors and cable, hence you will find no tape wound sticky side 
out. Normally I just use the commercial heat shrink.  The MMM stuff is 
tough and normally only the larger size is needed, but if you have LMR 
or CNT 240, or RG8-X Then a short piece of the smaller diameter tube 
will give a good seal.  The big stuff shrinks from 0.88 inches to 0.22 
inches so it should cover a PL-259 with an adapter to RG-6, or the 240 
series cables.  OTOH I'd use an additional short piece of the small 
stuff with RG58 or with the 240 series and then shrink the larger size 
onto that for "comfort"

I've never had a problem just taping them, but I strictly use the 
flooded heat shrink unless I can't get to the area with a heat gun.  I 
take the heat gun up on the tower as well.  So even at the bulkhead 
connectors at the top of the tower you'll find "flooded" heat shrink 
applied directly to the cables and connectors.

Just pull 'em up with a tag line.  Once you get used to them they are 
pretty much like using any other tool up there and yes, I do have some 
long extension cords which I tie off  next to the work area.
