Goulet Micro-Mesh (12000 grit)

I should have started here to begin with

Very effective product.

I've used my recently purchased Micro Mesh to polish a couple of my scratchier pens and to actually reshape a couple of others. It's more aggressive than I thought it would be--polishing requires a lighter touch than I anticipated, but that just means it's effective quicker. Using this following some reshaping with 2 and 3 thousand grit sandpaper has made a couple of my inexpensive pens write very nicely. I'm very pleased with my purchase and as advertised, I think this one piece will last a long time.

I need more experience to use correctly

I tried to use this on a stubborn nib and it seemed to work somewhat, but I am no where near a nib smith.
