I use stainless steel myself. I’ve used Formica years ago, and it’s not bad, but doesn’t hold up real well over time.
But if you are having issues getting the bow out of the form, or limbs out of a form you may want to wrap your limbs in heavier plastic than Saran Wrap. I use a painters plastic from 1-3 mills thick. The thicker plastic is much easier to get off the limbs too.
Another issue may be eliminating washers or guides holding your glass in place on the edges. Just drill some 3/8” holes about an inch down from the edge of the form and use heavy duty zip ties to hold the bow in place. This is also really helpful to keep things from sliding around too much once you get your system down. It’s really nice getting recurve limbs into a form too. Food for thought…
