A fiberglass sheet slightly over 1/64"??? Man that is thin.
In answer to your question... I think that hand sanding with the paper in a sanding block would be your safest (For operator and material) alternative. Even then, the sanding process is going to be a very delicate task. I would be afraid to use any machine on something that thin.
Use the right tool for the job.
