This is gonna sound strange and I didn't believe it until it was shown to me but, you can strip any fiberglass fuselage with a razor blade! Buy a box of hardware store razor blades and go to town. Work the blade at a very flat angle underneath the paint and then just start stripping. The guy who showed me builds Madera racers for guys, I watched him strip a large Bearcat in about one and a half hours. I did it my self on a Yellow Spitfire and it worked like a champ. By the way, it had epoxy paint on it! The advantage is its cleaner and quicker than sanding and solvents. You may have to sand some small areas where you can't get the blade under the paint, but overall it works very well.
