On the control holes, I would back the Bondo with dowel plugs. Bondo is OK for filling pickup cavities, but there is still wood on the bottom. You can take a piece of dowel and cut it with an X-Acto razor saw wafer thin and glue it at the bottom of the hole, let dry and fill in the depression with Bondo leaving a slight build up for sanding.
