>  Steve,  Is the butyl rubber vapor wrap the same as  Scotch rubber mastic 
tape 
(2228), which is available at the big box  stores?  I have been wrapping 
joints 
in two layers of reversed Scotch  88/33 (sticky side up), then overlapping 
with 
the rubber mastic tape,  protected with another double layer of 88 or 33.  I 
only have about 5  years experience with the mastic, but connectors that I 
recently exposed  looked like new.


         That's a James Dandy  way to do it and highly recommended. 
 
        As far as the mastic tape,  there are many varieties of butyl rubber 
and other materials such as mastic.  There's also a product for plumbers and 
one for florist shops. 3M probably makes  a dozen or more rubber products with 
different voltage and temp ratings, etc. so  it probably doesn't make much 
difference which one you use. Just make sure you  use your tape-vapor wrap-tape 
scenario and you're good to go.
