Well, what did you use to bring it to 800? If you used sandpaper, this could explain why the ball lost it's luster. Storm particles seem to be softer that some of the other major brands, in my experience. You should only use a scotch brite or abralon pad to scuff the surface, from what I've been told.
Hope this helps.
