You can sand laminating polyester resin.
In fact it's often necessary on many layups, where an air bubble
forms between layers due to uneven tension in different sections
of the woven roving. Can't sand the laminating resin with fine grit.
On the few hulls I've had to re-stringer, a 36 grit disc
on an electric grinder removed the problem and feathered the edges.
