When I stripped a polyester fuselage I used a product specifically for fiberglass. I can't remember the name of it----I bought it at an automotive paint/supply store. I don't know if it would work on an epoxy fuselage. From what I've been told if you use the wrong stripper you could ruin your part. I've also used a razor blade to scrape paint off with good results. You hold the blade about 90 degrees to the surface and scrape like you would if you were removing a parting seam line. If the paint is brittle and not too thick the razor blade method works pretty well. Good luck!!!!
