I don't know if this will help but on the hood of my pantera there were many cracks and pieces of fiberglass broken right off. Went to wal mart got some bondo resin and some fiberglss sheets, pretty much just cloth. put down some resin, a sheet of cloth, some more resin and let it dry. you can do this a few times if you want it extremly strong. After that just sand it, paint and there you go, better than new. Worked wonders on my pantera. Going to have to do it to my crappy little e-ton as both front fenders are held on by duct tape right now. this stuff will work on almost any material and is pretty cheap and somewhat easy, it has to be warm were your working though. Here's a picture of what it looked like before paint.
Hope this helps
