Bill,
I would be very difficult to apply this kind of finish on a larger scale.
You would need a clean room not unlike a chip manufacturer.
The smallest dust particle, if trapped, magnifies the imperfection.
It is difficult enough to do it on a smaller scale.

Udo

Monokote is just the model airplane brand of a heat shrinkable plastic
film which is probably avialable in widths and thicknesses that are big
enough for glider wings. I've wondered if somethng like this woldn't make
an inexpensive refinish process.
