Polish tomorrow with deemed then onto sanding and electronics mock-up
I presume that "deemed" was supposed to be dremel .
FWIW, use the dremel on the lowest speed you can that still effectively polishes. You don't want the frets heating up.

I can't remember what speed I have used, as I stopped using mine quite a while ago and do it all by hand now. However I have made a DIY fret polishing tool from a hand-held-grout removal tool. It saves my fingers from receiving all the pressure.
