Most of the Classics that I know of needed 1/4" of filler around the base of
the fin, where it attaches to the stub on the fuselage. Now different on the
XS of course.
Elsewhere, the average filler depth was about 1mm, depending how straight
things are required. Anyway, the wing droops under its own weight by more
than 2mm, so don't try filling-out that!
Personally, I made a contour map of the flying surfaces before filling so
that the low areas could be filled preferentially and so that I knew where
the highspots were, these obviously being the first to go bare during
sanding.
Whilst its important to sand-off all in one go, its not actually critical to
get all the filler on in one go; meaning that it can be built up in
successive layers, so long as there is no sanding done between each layer.
