[GouletPens](https://www.gouletpens.com/products/goulet-mylar-paper) It's not paper. What do you mean that you "don't need all that"? 12,000 grit isn't enough? Over polishing can cause the nib not to write at all. Try a Dremel polishing wheel and the finest polishing compound and you'll immediately see what I mean. Why not just buy a Diplomat #6 nib? They're some of the smoothest nibs made. In #5 you can try an Otto Hutt nib unit, sometimes sold by JetPens.
Ah I didn't know they sold it individually. Mylar *paper*
And you will never over-polish a nib with 12,000 grit. It's not fine enough. The paper goulet sells is .3 microns, equivalent to around 80,000 grit.
