I haven't had a chance to test it, but I feel that a slower speed wheel should be used for the final step(s). I think fast speeds make the wheel fibers slap the metal too hard and cause scratches no matter what compound you use. You could also try a canton wheel.

In _my_ experience the blue doesn't do much except that it's good for polishing plastic. I've also tried the talcum thing with no success, but perhaps others have had better luck.
