You are correct.
But I expect there is a major time gap between when the paint rmover will
loosen the old glue and when it will attack the polyester. It certainly
didn't have time to attack the surface I was working on. And was washed off
with water after scraping.
It's been a dozenyears, so I'm a little fuzzy, but I think i may have
removed as much as I could with a heat gun (got to be careful with that as
well), and then cleaned up the remainder with the paint remover.

My last boat had a foam backed vinyl on the interior. The foam dried up
and
fell apart, resulting in the vinyl falling off, but leaving a coating of
glue and the remnants of the foam on the fiberglass surface. I removed
this
residue with a variety of methods. A heat gun worked, as did a thick paint
remover (making sure to scrape off and wash from the fiberglass as quickly
as possible).

I replaced the old with a closed cell foam material. First used solvent
based liquid contact cement, but I think you will find as I did that this
can slightly dissolve vinyl material.

I then discovered a water based contact cement from 3M. IIRC, it was about
3
times as expensive, but was so much thinner that it had maybe twice the
coverage. Fumes were so innocuous...almost could say it smelled good. I
ordered this product from a NAPA store. Gallons only. Get several cheap
brushes as they get gummed up.

You mention that if used paint remover should be washed off quickly.
Not to argue but I believe that you should emphasis that most common
paint removers will destroy fiberglass and should be used very, very
carefully.
