Got bad news for ya. The only really good way to get a mirror polish finish on metal is to grind it--admittedly with a really fine sandpaper/grinding wheel/buffer/other piece of metal, but you're still grinding it. You're not seeing the specks because they probably aren't visible to the naked eye, but I'm willing to bet they're there. There's a number of factors that could play into whether or not it continues to grind, like how much it's work-hardening or how smooth the other surface is.
But like I said, you're probably already grinding it a little and don't even realize it. That's why you have the offseason--to test things out and to learn what will and won't work and to figure out what you'll need spares of.
