I read an audio tape site that as part of a

new finish (brand name polish ?)
This was after cleaning for a stickiness problem, not a shedding problem
though.
It's actually called Nu Finish and was manufactured by 3M, but now done
by someone else with a reformulation. By all reports, I've read that
it's not as good as the old stuff and indeed, my experience does seem to
bear that out (on 1/2" tape anyway). You might be better off trying
some plain old Cocamide DEA, which is a fatty acid used as a lubricant
by some manufacturers. It's available in bulk.
I believe that NuFinish mixes a fatty acid up with a fine silica for
their product, if the MSDS is to be believed. I don't recall if a
surfactant was part of the witches' brew.
Baking alone should work for now.
