Having coverered the flaps, fin and stabilators with expancell (or whatever
it was that the factory supplied in 1997) before switching to superfill (for
the ailerons) my opinion is that the cost of superfill is worth it if you are
interested in saving time. In my experience the superfill sands considerably
easier. There are other advantages such as consistancy of the consistancy of
the mix (couldn't think of a clearer way to put it). What it means in practice
is that each batch of superfill sets to the same hardness as other batches.
Others have mentioned further merits (lightness for one).
