Perfect for making finishing harder. Use the plastic wrap next to the
wax paper instead.

UH

Beeswax furniture polish is also good: its my favourite release agent if
I'm laying up small items on moulds made from car body filler. A couple
of coats, applied fairly liberally and rubbed down when works for me.

A single coat of the John Lewis Partnership beeswax polish (a thick
paste) applied to a scrap piece of bare, unvarnished, veneered shelving
and allowed to dry before I laid up a couple of layers of glasscloth
wetted out with SP113 directly on the polish was enough to cause an
immediate release after the epoxy had hardened. I stuck a knife blade
under one edge and the whole test patch, about 50mm x 50mm, popped right
off the wood.

As always, try any release agent on some scrap material before using it
for the real job. This advice probably applies in spades to furniture
polish: I always use the John Lewis Partnership beeswax polish but I can
well imagine that other brands may give different results.
