The video you all posted about water proofing foam board with brown paper and polycrylic was way to messy and cumbersome. There is a much simpler solution; oil based varathane (not water based varathane). Simply wipe on a thin coat with a rag or paper towel, wipe off the excess, and when its dried you have a water proofed foam board that is now easy to paint. You can spray paint all you want without worrying about wrinkles. See the photo attached of my wing section of my Simple Storch. I used paint sticks hot glued to the fuselage sides to reinforce the wing saddle and the skewers for the rubber band hold downs. I also used Popsicle sticks to reinforce the servo mount area for a more solid servo mounting and on the elevator to strengthen the elevator halves. From Lewis Howard
