Pro shops tend not to finesse balls when we ask them to polish balls for us. We tend to be more particular about our own balls and our own procedures.
He might have put a little too much polish or too much pressure on it. Since stock is 4000 Abralon + polish, you might want to sand it to 2000 Abralon,then sand it to 4000 Abralon, using relatively new pads. AFter using the 4000 grit pad, it should not look the least bit shiny. Then apply a very light dose of Renew-it.
That should be closer to stock.
