Pete, does Z2 on the windscreen have the same effect as Rain-X?
My experiences with applying a sealant to the front windshield varies. Some applications it's great and water beads right up and off and other applications result in wiper chatter.
If you want to try it, I suggest applying it to a small (6"x6" ?) section over on the passenger side and see how it works for you.
Having something on the windshield, whether it be a sealant or Rain-x or whatever definitely helps to prevent/reduce water spots.
