I'm sure it is possible to make granite shiny. I'm not so sure that flat and shiny go together.
I had my plate re-calibrated some years ago. They lapped it with diamond dust on top of a much larger plate. The result was a matte finish that was duller than before, but also flatter than before. I think polishing it to a mirror finish might actually make it less flat. I'd be tempted to try something like car wax. The film should be very thin, so it should have little effect on flatness (and you could probably remove it with alcohol or something). -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
