We've been very happy so far with Rejex. Still beads up well after a almost a year, since application, of full time cruising up and down the east coast (Massachusetts through Key West). Less "ICW Mustache" than last year too, and what there was, as well as other types of smudges, cleaned right up. I wonder how much difference there really is amongst the various popular brands, but not having direct experience with Pro Polish or Zaino, can't compare.
