A plane like that deserves a fiberglass/paint finish. See if your dad knows how to show you how to do that. Or better yet, use MinWax polyuerthane instead of resin to adhere the glass. I haven't tried it myself yet but a lot of the guys in the composites forum swear by it and it is much lighter and easier to work with. I can track down more info if you need it. It's Minwax Polycrylic and you can get it at Lowes. Water based and sands easily, low fumes too. You get a beautiful finish that's fuelproof when used with a good paint. Might need to find someone with some painting gear (airbrush or small spraygun). Build the plane while you decide how to finish it.
