When you talk about glass, are you talking about building a positive and negative form for the fairing? I would not have a clue how to proceed. I'm thinking it would take time and skill and you would need shop room and no small amount of supplies. For aluminum, I just make trial patterns out of cardboard, cut, bend, and rivet. I've got zippo room, no heat, and with winter arriving, cure times for glass would be brutal. Don't get me wrong, a nice glass fairing would be far superior to what I can bend, but like Dirty Harry once said, "A man's got to know his limitations." And heck, I'm in it for the fun of doing something challenging and perhaps creative... within my amateur skill set... and my expectations are low. I'll take pictures of the effort.
And guys, I do appreciate all the tips.
