trailing edge depression – sanding the micro fill

In chapter 19, page 6, we trowel some dry micro into the T.E. depression in the bottom skin. That part of the bottom airfoil is slightly concave, so when it’s time to sand down the micro fill and blend it in with the surrounding surface, I can see the potential to accidentally sand into the G-to-G aft edge and inadvertently thin it out too much. While the dry micro is much more sandable than fiberglass, the angle of that glass TE brings it to an edge which would make it vulnerable to over-sanding. (That’s my guess, not having done this step yet.)
Besides ‘be careful’, does anyone have any particular advice, tips/tricks, dos/don’ts for sanding that surface?
