non-stick jig

I tried the wax paper suggested. Works OK, but some stuff still sticks to it. Thought I would try Saran. Works good, nothing stuck. OK, not really... I thought I would bookmatck a couple of small panels. First set went well, undid wedging clamps after glue set up and set panel aside to cure. Applied glue to next set and wedged in place. Came back after a couple of hours and pulled panel out. D'OH!!! The Saran had bunched up and gotten squeezed in the joint! The other two solutions that look like they will work well are 1) using a new, *smooth* nylon cutting board to lay up the bookmatch panels, and 2) using a discarded-but-not-yet-trashed heavy poly shipping bag the cat had been playing with. It looks/feels like very heavy visqueen. Nothing, not even epoxy or gorilla glue seems to stick (so far!).
