2mm tungsten final grind with 1000 grit emery cloth.

What's good enough for hobby work?

lol that's plenty good. At work or in the field sometimes the only thing handy to clean up a tungsten is a 4-1/2 inch grinder with a hard wheel. Those are so rough you can see the grooves at arms length. But they weld!
