The 0.1 um film feels very smooth when I put an inked nib on it. I expect hardly any material removal at all, and that it would take a long time of polishing for the nib to be noticeably smoother. But it does make the nibs scratchy very quickly.
Up til now I used a piece of smooth leather with some well-worn polishing compound rubbed in to it. Lightly polishing the side of the nib tines first and then two very light strokes at the actual writing angle to remove the burr but not too much get baby's bottom. It does most of the nibs very well, but the Pelikan M1000 simply would not become a smooth as I would like. And I do not dare to take it too far.
So I thought I final brush-up with an ultra-fine polishing film might do the trick.... but alas, just the opposite.
@Honeybadger: I will 'wear in' the film with a knife, and try again with some other (cheap) nibs.
I removed the adhesive backing and stuck the films to a strip of MDF, which is smooth and very flat. Then wore it in by using a knife edge. Cleaned the surface, and tried again with a Moonman pen/nib.
With 'figure 8' I mean also rotating the pen over it's axis, to get a spherical contact surface. No pressure.
It does make a difference, the nib does not get scratchy immediately. The nib I used was already very smooth, times properly aligned, and it did not deteriorate. So far so good.
Tomorrow I'll try some other nibs that I would like a bit smoother.
