You might as well skin the entire wing in ply and use a minimal glass
layer as a protective coating. Either way you are going to end up with
a much heavier wing.


Having read his book, I think that is exactly what Bingelis did, with
either the wing, or the fuselage, or both.

The advantages were a smoother surface, though I daresay proper
wood finishing technique would produce as smooth s surface
with considerably less work and wieght, and improved resistance
to the elements.

I believe he said it added 10 to 15 lbs to the plane.
