Gregory, I found this on a vendor's site. I never actually used the white myself. As a matter of fact I didn't see it on the Shurhold site. I may have just missed it.

Note: Buff Magic pink formula is infused with jeweler's rouge, a red amorphous powder consisting of ferric oxide. Jeweler's rouge is used in polishing glass, metal, or gems, making the pink formula preferable for metal polishing applications. The pink formula is also safe for use on fiberglass applications. White Buff Magic is recommended for use on fiberglass only.
