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 !

Interestingly I've done pretty much exactly this recently. I think the
plastic sheet is essential and you need few wraps. One suggestion on another
forum was to put several long thicker strips of plastic under the wrap
....protruding from the end so they could be pulled out and give a little
room for the wrapped plastic to slide and twist as you remove the glass
tube.
