I’ve had good luck with CitriStrip. I used it on a fiberglass spinner. Since it was base/clear coat automotive paint and quite thick, I scuffed it really well with some 60 grit first… just enough to scuff the clear well. It didn’t remove all the paint but softened it to the point where I could remove it with a stiff plastic scraper.
The label says it’s not for use on fiberglass, but there was no damage or softening. This was epoxy glass, not polyester.
Aircraft Spruce sells some Stuart Systems stripper called EkoStrip, I think. I have a sample bottle but haven’t tried it, it was bitter cold when I got it and most strippers like warmer temperatures. Something to do with the glitter and coconut oil… oh, wait. Wrong strippers. Still, none of them
Work well when cold.
