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?





Bruce, not an expert. but I have personal first hand experience that
repair specialists use acetone routinely to clean composites when
working with gelcoat and uncoated GRP/foam. If you soaked the composite
or left it on there a long time, I could see where perhaps it could
damage something underneath, but a brief exposure for cleaning would
appear to be OK.
