Have you ever tried Rain-X? My Aquapel application is getting worn now, so I can't remember what it was like when fresh, but all I DO remember was I got a lot less hazing with Aquapel than I did with Rain-X.
I'm not sure if this would help much, but try cleaning the glass with some 20/20 and clean your wiper blades (gently!) to get dirt or oil off of them. Just don't be dumb like me and keep scrubbing madly until you wear off the black coating on them, or Aquapel will cause them to chatter horribly.
