I notice on the bottle of polyester resin I got that it says not to mix
the stuff in a waxed paper cup. It's in bold too, so it seems
important. Not only was that how I was going to mix it, but I was going
to lay the material on some wax paper so it won't get glued to the
floor. I have used 2 part epoxy in this fashion and it has worked well
(the epoxy cures and was too flexible, so I'm using polyester.). Does
wax react poorly with polyester resin?

One way of producing a polyester gel coat is adding wax. This holds
off the air from the surface, so it does not stay tacky.
Dissolved wax is not the best ingredient for other layers however.
