Take a look at the description of the Meguiar's product. It's a polymer and it's designed to left on the surface of whatever you've treated. Diamond may have recommended it; but it seems to be pretty clearly outside the rules of the game, which doesn't allow residue on the balls. I be interested to hear their explanation for recommending this.
There have been several threads about ball polishing, one long one within the last few months.

After reading this, I believe you'd be hard pressed not to run in another direction for a ball cleaning product.[/QUO
