Hello All,

I'm taking my first steps with platinum, having worked with silver and gold for some time now.
I understand the need to prevent contamination, so keep files, sandpapers, etc separate.

The main area of advice I need, is in polishing. Firstly, I often use a barrel polisher with steel shot for my silver and gold, and finish with Luxi blue/white/orange with buffs on my Foredom.
Is platinum suitable for barrel polishing, and with steel shot?
Will a Foredom motor polish platinum ok, or will I need a larger diameter buff?

Thank you for any tips!
