Dig up the MSDS for it if you can. It should tell you something useful. The one caution about all of the rouges that have waxes in them is that the wax can obscure the scratch pattern and make the polish look better than it is. Of the "rouges" out there (used loosely by some to describe all buffing wheel polishes), you can bet that the green has chromium oxide in it, the red has iron oxide, the white has aluminum oxide, etc, but you never know what else is in the stick if stuff without looking at the MSDS. Most of the stuff that is not targeted to jewelers, etc, has some sort of cutting agent in it above and beyond the base oxide that determines the color. The "microfine" compound has more al-ox in it than chromium oxide, and bigger particles, the iron oxide "cut" polish that I got from mcmaster carr has aluminum oxide up to 10 microns in it, etc.Quote:
