I would be very careful about using Acetone on a glider, depending on the
construction you could do damage. Reliable sources indicate that acetone can
penetrate the structure and damage the foam core in GRP/foam sandwich structures.

Not being a composites specialist I can't comment. Just try to use something a
little less aggressive - like MEK.

Any experts out there?

I'm not going to call myself an expert but MEK is a much More Agressive
solvent on many substances. If I recall correctly many gelcoats are
styrene based. MEK will dissolve styrene quite readily, actually it is
was is used for model glue.

MEK also seems to disolve brain cells too, which may or may not be a
problem depending on what memories you want to keep.
