Thanks guys. The ball I am using is an AMF Hype reactive, and all it says is 600 grit with 2000 grit polish.
I don't think I have ever used a gritted polish. Where do you get that?
I don't think you ever used a polish without some abrasive in it.
That's how they take surfaces from 500, 1000 or 2000 grit to 5000 and 5000+ grit, which is the grit level at which most polished balls' surface exist. Right now, to my knowledge point, Motiv Gel polish has the least abrasive in it. Lane#1's Secret Sauce has the most abrasive in it. (I consider Royal Compound, formerly known as Rough Buff, and Storm's Step2 to be "compounds", not polishes, although when they take a surface to that 5000 grit plateau, the ball will take on a shine.)
Those polishes which people term "non-abrasive" have the least amount of abrasive in them, but all polishes have abrasive to a lesser or greater degree. Remember that polish is NOT a coating like polyurethane or varnish or lacquer. It is a smoothing out of the highest peaks of the surface to at least 5000 grit. That's the point (grit level) where a surface begins to shine, to look polished.
