When I am doing small sheets and I want them smooth or pre gelcoated, I start with a 2'x4' sheet of dry erase board from Home Depot for $10.
Wax it or spray PVA.
Spray gelcoat on it, let dry for a few hours (not several days!!!!! - I learned that lesson)
Lay up glass, put peelply on back (great bonding surface & no blush w epoxy, allows full cure w polyester or VE) and let harden
Pops right off and glass smooth (unless the wax or PVA is too thick/uneven)
