Thanks guys!

LBD,
I just touched these to the belt sander (80 grit) until I could "feel" I was almost getting the tape to make contact.
This left a small bump of resin and these lids being small I just used my ROS (80g) to work down to the tape without messing it up. Easy enough to peel it away then.

Found a scraper worked most excellent to shave down the remaining resin (and bits o' tape) to bare wood.
I always inlay deep enough to have meat left for final sanding cleanup.

For unfilled. no real need for tape IMO, but a scraper (or box cutter razor blade) makes quick work.
