Film plate question

[Jayk]

Hello,
I picked up the flattest marble tile I could find at the home depot. Seems I really confused them by just wanting to buy one, so they dis not charge me. when I attempted to hone on it, i felt a few so small bumps with the razor. A close inspection revealed that the tile has some very small scratches on the surface.

Would it be a bad idea to lightly go over the time with some 2000 grit sand paper on a sanding block to smooth it out? Or would I be better off trying to find a new, perfectly clean surface?

You know what's a super flat surface for film? Glass.

In fact, I use the flip side of a Shapton GlassStone 1K with cut-to-size films for the world's smallest honing kit, and can go from bevel to strop in a jiffy.

That's a good idea to use the glass part of a Shapton. I use the top of a hone.
