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 !


I don;t believe that you could get the glass off the PVC. I have made
fiberglass tubing by molding two halves inside PVC pipe split
lengthwise and using several coats of mold release it still took
significant prying to get the halves out of the molds.
