SigKavalier (nice airplane btw), the best way to do this nowadays is either lightweight silkspan (yep, the old paper stuff) or very light fiberglass cloth put on with Polycrilic (water-thinned) polyurethane. one coat to adhere, another to fill, then color. Very light. On the nose, you might put two layers. Nylon strapping tape is good, too, on the wings.

A strip or two of carbon fiber or a 1/4 square spar -- hard balsa or spruce -- and the wing won't break-- well, it will, but let's not get silly about it.

I like fabric and paint better than film because ist's easier to patch dings and seams don't come loose.
