Justin,

have you thought of Sig Koverall and dope?

You first put down the adhesive, and then cover with their fabric, Koverall. It shrinks like film, but it is an open weave. You can then fill the weave with a finishing dope, and then final spray with dope colors.

This method is kind of like glassing, but you will not get the shiny high gloss surface. And since this is a corsair, it will be more realistic. You will not have to worry so much about working times, nor mixing proper proportions.

You can cover easily over open structures this way and over curves with no seams. Just fill any seam areas with dope, sand smooth and that is it.

Since the Koverall shrinks like film, you do not have to worry about bubbles and adhesion as you do with glass. Glass has to be stuck down to the surface with epoxy, and a bubble under the glass can be difficult to fix.

With Koverall you basically put a light coating of the adhesive over your wing for example. Tack down the edges as you pull it tight. Then hit it with a heat gun to shrink tight. Next run your covering iron over it to stick it down to the balsa. Then just fill with dope, sand, fill sand, and paint with dope color of choice.

Either way, best of luck!
