I've finally completed getting the deck and hull together and finished the inner/outer seaming. I had some issues with the fill coats coming out smoothly primarily because of using slow curing system 3, I'm convinced. I probably didn't scrape enough epoxy off during the coats and had issues with runs and general mottled looking finish. I'm not really that concerned about it now since I can smooth things out during final finishing. I have a few questions about generating a smooth finish. Since I can't do a complete coat, top and bottom, should I use painters tape to purposely define a stopping point just below the seam? Should I use the fast curing resin at this point, I assume this is a yes? Should I apply the final coats with a brush or roller? Since it is December, 50F in California, is it okay to do the final finishing at this temperature?

Thanks as always for the help.
