Newbie Question -- Should you burnish cross-grain a maple neck?

[SchiefDavid]

I just got two lovely roasted maple necks today - one all maple and one rosewood.  I've usually tru-oiled my necks, but want to try burnishing these.  So a newbie question: when burnishing the maple fret-board with grits 400-2,000, is it OK to sand across the grain?  My grandfather the woodworking carpenter would have a cow, but how else can you do a uniform job with the frets in the way?  I appreciate everyone's help.

You generally don't burnish the fretboard due to the frets being in the way.

If I do a 2nd build, I'm thinking I will order the neck from Warmoth without frets to burnish the fretboard along with the rest of the neck, then have it fretted locally after.

I like doing nothing to a roasted maple neck.

You never sand across grain, no matter how fine. To burnish fretboards, you order the neck without frets, burnish the 'board, then install the frets.
