[V8] Self-fusing Polymer Tape

Powerbond is similar but not the same (rated -27° to 260° F) -- so IMO it's
more appropriate for coolant hose leak repair, among other things.   The
other stuff also goes by the name Tommy Tape and is available from ACE and
True Value hardware stores (look in the electrical tape section).  It's a
self-fusing polymer tape.  Tommy Tape is superior to Powerbond in that it's
continuos duty range is -65° to 500°F and if wrapped properly has a tear
resistance of 85PSI.


Of note:  At the recent ACNA Nationals in Brainerd, MN, the IC to throttle
body hose of my Urq split in my first run group :-(
Nobody had a spare hose (almost unobtainium anyway).  But I was lucky enough
to find someone who had a roll of Tommy Tape.  Just in case, I also
duct-taped over it.  For those who've used duct tape, you know that it will
split at 7PSI and doesn't like the heat.  Well, the  Tommy Tape held 12 PSI
and probably would have held more (I may still test this now that I have a
new replacement hose).  Anyhow, I was able to drive my Urq the ~800 miles
back through the Upper peninsula of Michigan to Metro Detroit without
incident.  I made sure to find some emergency spare rolls when I got home.
A must for your toolkit, IMO.
