I've stripped paint from 2 corvettes. Use chemical stripper and a plasitic bondo spreader to remove the paint after it softens up, wear face mask to protect against splashes. Stripper won't take off the primer you'll need to lightly wet sand with 400 or 600 paper.
I've seen guys sand off the paint or use hard edge scrapers with the stripper, both did damage to the fiberglass. I'd stay away from those IMO.
(I stripped the red '68 Coupe and the white' 66 Coupe)
