I like to use 3/4 or 1oz glass on the fuse and 1/2 oz on everything else with West Systems epoxy. The trick, well my trick, to keeping things light is to use those little throw-away foam rollers. Get the higher density white foam ones that slip onto the metal and plastic handle, the cheaper yellow (low density) foam rollers with cheap throw away handle do not do so well.

I sand the foam (on the aircraft) and vacuum carefully to remove all the dust. Do not forget to vacuum the work area as well, the foam dust has a nasty static charge and will contaminate your work when you least want it.

With the area cleaned and prepped for glass work, roll out your glass and cut two pieces (one Top/one Bottom) on a bias (fibers running at 45 degree angles to the center-line) cut them well over-sized for extra material to grasp. Be aware the glass will tend to stretch and distort when cut on a bias, but you will not get wrinkles or puckers when applied properly.

Next I dust (just a light spritzing) 3M 77 spray adhesive onto the bottom half of the fuse or wing, do this outside or where you do not mind the spray adhesive getting all over EVERYTHING. Now carefully lay the glass down on the fuse/wing and smooth it flat working from the middle out, ensuring good contact. On the fuse I pick a line about half way around and carefully cut the glass with a very sharp blade. I do not cut much into the foam, only deep enough to cut the glass. On wings use the leading and trailing edges to cut along.

Now go back outside and dust the other side with the 77 spray and repeat the glass step as well, except overlap the first layer by about a 1/4 inch or so. Now you mix up a couple of ounces of resin which I do not like to thin, proper laminating resin will be thin enough. Stir it thoroughly and let it stand for a minute or two, this is called dwell time and allows the resin to "Homogenize" kinda. You will be using slow resin of course, no need to rush yourself needlessly.

Pour the resin in a plastic or foam plate and break-out your foam roller, saturate it well and go to town, you want to move the resin around quickly and evenly trying not to spend too much time in one area as the glass will start to lift. I do this in two stages which allows me to rest the fuse on one side while the resin cures then do the other side and let it cure. Sometimes, I have the ability to hang the part from the ceiling and do the whole unit at once.

Of course then begins the fun of sanding, filling and painting. Your finish applies here...

Good luck, Wolf
