the way i do it, and with desirable, "passable" results is to fill the holes after you apply your sealer, try to keep your fingers clean by wiping on a rag, THEN proceed to sand the sealer, followed by laquer.
never heard of using cornstarch, but if that works for you, good, i use whiting powder, and i add enough of the whiting powder to the putty almost until it is crumbly, but i press and knead it into the putty so its well mixed.
I find that left over "smears" is from messy fingers and a combination of not enough whiting powder. Every painter does things differently, so whatever works for you go for it.( sorry i didnt mean to repeat others in the use of whiting putty, becuase i hadnt read the others response to ypur thread)
If you come forth with a 5th on the 4th, you might not come forth on the 5th
