Mark,

Traditional sanding sealer contains some kind of "sanding aid," usually
zinc stearate.  If you build up too many coats, it will look cloudy after
you spray on the topcoat.

PianoLac Sanding Sealer/Barrier Coat/Pore Filler contains no zince
stearate; it is totally transparent.  The solids left behind are encased in
an acrylithane resin.  It sands easily and fills the pores in 4 or 5 coats,
depending on the nature of the grain structure.

I have had the experience of using 2 or 3 applications of traditional paste
wood filller, 3 coats of sealer, and 4 to 6 coats of topcoat, and still the
pores aren't filled.  Pinholes and orange peel are still evident.  SS/BC/PF
not only functions as a sealer/filler, it also doesn't raise the grain, and
it prevents the topcoat from raising the grain.
