I, too, polish platinum every day, and I agree completely with
Sarah Graham’s 4-step polishing program. I prefer the Japanese
compounds from Frei & Borel, but that is a minor difference.
But I have made a discovery that makes the first step (
agressive polishing with 800 grit ) a lot quicker. Steve Frei
gave me a 4" rubber wheel to test this summer and, unlike all
the other rubber wheels that I’ve tried on plat (they tend to
burn against the metal), this one works great. It is made by
Airflex , Frei & Borel no. 110.256 (no, it’s not in the catalog
yet. Ask Steve) . It will remove fairly deep scratches quickly,
and I can almost bypass the 800 grit stage. The wheel sells for
$15.50, and if you are polishing a lot of platinum, as I do, you
may want to invest in a couple of wheels so that you can shape
them to match various contours. Steve says that a 7/8"
unmounted wheel will be available in the future, as well as
inside ring shapes.
