I don't think the colloidal silica effects the strength in any negative
way for this purpose.  You can mix it to any consistency you want.  For
the final fit of pinblocks to the stretcher, I mix it to the consistency
of mashed potatoes (light ones).  It won't run at all but can still be
squeezed out easily.

    I've been using the west systems fairing filler which is a decent
color but it still quite fluid even if I add a fair amount so assume
adding  C.S. turns the consistency to something like play dough? How
does it effect strength? Not that matters much in this application

Mix the epoxy with colloidal silica, in addition to your other filler of
choice (available from West System).  You can make the epoxy as thick as
you want it and it will stay in the notches without tape.  Over fill
slightly and sand it flat.  It's good stuff to use for fitting pinblocks
as well.
