Still don't know the best approach to this. All I know is that I've managed to screw this one up multiple times. As I often seem to demonstrate, "Good decisions come from experience. Experience comes from bad decisions."
Here's a picture of a brushed on waterlox original s/f top:

The rest of the piece looks fabulous.
What is the best approach to fix these brush marks:
1.) Just brush another coat on top of this. (In my experience, the marks still show.)
2.) Sand this coat level using x grit sandpaper (please specify "x") (In my experience this doesn't work so hot either, unless you sand off below the entire coat).
3.) Another method (please send ideas my way.)
This is why I have gravitated to wiping on coats of Waterlox, but I just had a real disaster with huge numbers of witness lines after rubbing out a piece, so I'm looking for level thicker coats this time.
