   You can use regular solvent grain filler under vinyl sealer and then topcoat with most catalyzed lacquers.  Just don't try regular graion filler and then topcoat directly with cat. lacquer.

   Several companies make catalyzed sealers for use under catalyzed topcoats.  These are pretty popular among the commercial finishers I know, because they do a pretty good job of filling open grain.  For me, it's a lot of steps and a lot of sanding, plus, there is some shrink- back as the finish cures, but that's just me.  A lot of people swear by catalyzed sealers.

   I wouldn't recommend the polyester on small projects, although it does work.  Seeem lke too much bother, what with the super short pot life, and all.

   Trying to fill with regular sealer or lacquer is wasted effort.  The finish is only 25% solids or so by volume, and even when it feels dry, there is still a lot of solvent left in the finish.  As it cures over a period of a few weeks, the finish will shrink back into the pores, leaving an open grained look.  The only way to avoid this is to let the finish cure out for weeks before final leveling.

   On technique I have used is to use sanding dust from the final sanding (220) mixed in a paper cup with a small amount of full strength varnish applied with a putty knife.

   Works for me on QS Oak.
