We really have it easy as far as fairing goes, compared to other building techniques.
This after seeing a couple of other builders sites where fairing means covering fabric overlays and creating fair curves in all planes, some times this takes months of continuous work. In our case it takes weeks of sporadic effort because we keep putting the task off!
There is still a substantial amount of sanding to keep avoiding for a lot of reasons. A quote from a fellow builder says “it is after all, a hobby”
Bob’s designs with duflex panels or for that matter any design utilising “tortured” flat panels mean most fairing is blending the taped joins.
The big advantage with duflex is the ‘Z’ joint which eliminates a huge amount of joints to be faired.
When we have had some time (and inclination) over the last few weeks we have been using the Makita BO6040 and the Carbotech extraction to remove most of the filling compound to fair the tape edges and overlays. The work between the joins of the bridgedeck-chamfer-shear panels transition is quite difficult as its concave and narrow.
The images below are of the sanding so far.

The tape is at the top, the distinct line is the filling of the tape edge
