My secondary was wound on non-dried PVC.  I put it in the lathe, applied
a fairly thin layer of West System epoxy resin, and then wound the coil
while the resin was still tacky.  After winding, I applied more of the
resin and let the whole thing rotate until it cured, so I had no runs
or sags.  It works great, and I'd recommend the resin over varnish or
polyurethane, as it cures due to a chemical reaction with the hardener
rather than air drying like the others.  My .02 worth, anyhoo.
