I am working on my first glassed plane. I used .5 oz cloth and West Systems epoxy. I am very happy with the results. Here are some of the techinques I used. I used a sanding sealer on the balsa to limit the amount of epoxy absorbed. I thinned the epoxy with with 1 part denatured alcohol to 4 parts epoxy. I applied the epoxy with a brush and used a body putty applicator to squeegee off excess epoxy. I used a roll of toilet paper which I rolled over the surface to remove even more epoxy. To fill the weave after the glass has cured, I used a high build sandable primer. I sprayed the entire surface then used 320 grit to wet sand most of it off, repeating the process until I had a smooth, texture free surface. After filling the weave, I sprayed a constrasting color primer and sanded it down. This leaves color in all the low spots which I then filled with spot filler that comes in a tube from the auto parts store.
You can see photos of my build at various stages in my gallery.
