Sounds like you are describing epoxy and polyethylene .  Epoxy for the 
gutsy varnish and polyethylene  for the release surface.  I suppose you 
could include a glass cloth between the form (pipe) and the wire, to 
add strength.  You might need a press to get the pipe out of the 
coil, even with a release surface.  Not sure that this is cheaper 
than PVC pipe though.
