Here are pictures on the addition of fiberglass cloth.

1) Begin by tacking on a piece of window sheer over the top surface of the ailerons. The purpose is to provide a hinge surface.

2) Tack a layer of 1.6 ounce fiberglass cloth over the entire surface of the wing.

3) Tack another layer of 1.6 ounce fiberglass cloth over the wing tips.

4) Tack a wide (15.5") piece of fiberglass cloth around the center of the wing.

5) Follow with 3 more layers of fiberglass cloth (each getting gradually narrower) around the center of the wing.

6) Mix about 1.5 ounces of finishing epoxy. Add 10% more 91% alcohol to thin the epoxy. Drizzle this over one side of the wing and use a squeegee to spread out the epoxy. Do the other side the same way.

7) Place the wing between layers of nylon fabric (peel ply).

8) Put the wing in the vacuum bag and apply about 5" Hg vacuum to the wing.

9) It is getting cold at night so the vacuum bag was placed between layers of electric blanket. This warms the epoxy enough that it dries overnight.
