Working with Fiberglass
I've been building and flying models for approximately 55 years; most were balsa, and almost all of them could have used fiberglass reinforcement somewhere. I always seemed to have trouble cutting the fiberglass material without it developing rough or frayed edges. It was also difficult to get the material to lie down and stay on a model's fuselage (especially over compound curves) while I tried to coat the fiberglass. The resin's cure time caused problems when the piece of fiberglass moved or lifted up. I usually ended up with too much resin, bubbles to work out, and a lot of frustration.
