I cut the hinge slots for the ailerons and cutout the channels in the wing for the control rods. I am going to try Stix-it with the polyester cloth on the fin. I'll see how this goes before I cover any other parts. I applied one coat of nitrate to the fin and then a coat of Stix-it. I'll let that dry for a few hours and try ironing on a piece of cloth. I have used the cloth before with waterbase poly and it came out very nice. I shrunk it with a heat gun and it seemed to tighten up pretty well. We will see how it works with Stix-it and dope.
