If I were to wax the outside of a piece of 2 1/2 inch pvc pipe about 6 feet
long, and then lay up several layers of fiberglass and epoxy, would the
resulting tube slide off the pvc easily enough after curing ? Or would I
need to first wrap the pipe with sheet plastic or similar ?
Thanks !


No personal experience. Here's an unqualified opinion:
epoxy bonds to PVC. PVC pipe is a little wavy.
Taken together, I think this means removing the glass from the plug
would be tough.
Saran wrap is one avenue to reliable release I hear - or maybe a
good release agent - or aluminum foil I have heard suggested.....
