Ok, it's time for a lesson in glassing for you who have never done it. I'll show you just how easy it really is.
First, prep the surface. Sand and fill everything until it's as smooth as glass. I use bondo ultra (lightweight), glazing putty and light weight spackling paste for the pinholes and very small stuff. The bondo is used only around the cowl and tail fillets, where a lot of filling and shaping is required. Always use balsa wherever possible, sand it down, then putty and sand the rest. Don't just throw bondo at it or it will weigh a ton.
Next seal the balsa. You can either brush on balsarite and sand with 600 grit, or use hair spray (aqua net works well). Eitehr way, sand lightly until it's as smooth as glass.
Now you're ready to glass this thing. Cut pieces to fit the detail areas first, such as the pipe tunnel and the tail post. The fuselage itself is done with only 2 pieces, but the details need to be done first. The pipe tunnel is done with 2 oz cloth, and the rest of the plane is done with .6 or .75 oz cloth.
Mix some finishing resin and thin mixture with straight acetone. I use anywhere from 2-1 epoxy to acetone, to 1-1. It just depends. The resin should be slightly thicker than water.
Put your glass pieces in place, then using an acid brush, apply the resin through the cloth. It should become transparent, looking like wet wood. Spread it thin, but make sure there are no dry spots.
Leave an edge extending about 1/4" to 1/2". Overlap pieces if necessary to get all of it covered, then let it cure overnight.
