Now that I have a ball spinner, I would like to buy some polish that way I can polish my balls. I don't want to buy a polish that has a grit in it to where it finishes the ball to a certain grit (ex. 1500 grit polished) I want it to be a polish to where I can sand the ball to 1000, 2000, or 4000 and then apply the polish, and then I will I can have a 2000 or 4000 grit polished ball. I guess it would be nice to be able to put some on my plastic ball also. It has gotten pretty dull. So what do you think is the best polish to buy? Doesn't matter who makes it. Thanks
