Thought I would share my experiences of glass coatings, these are just my personal experiences and are probably biased by the type of driving I do and the type of roads I'm most often on.
RainX
Fairly chap and easy to apply and works well but for a very limited time.
With both of these you really need to make sure that the screen is super clean before applying otherwise you seal the dirt in as well. I polished mine using a DA machine with Menzerna 3500 optical polish, microfibre pad, and then cleaned it twice more with GTechniq glass cleaner, then cleaned it with 25%IPA solution in deionised water and then blew it off with an airline.
GTechniq G1/G2
This is a nano tech coating and is a bit of a faf to apply. overall if you do the job properly takes about 1/2 -> 3/4hr, lots of prep work to get a good finish. You need 3 coats 5mins apart then leave it for 20mins before using the G2 to remove the residue and polish it off. But well worth it.
When driving above about 40-45 and depending on the type of rain it just flies off the screen, a few months ago driving from Maidstone to Heathrow in the MX5 it was raining all the way and I didn't have to use the wipers until I got to the heathrow turnoff.
I've noticed that ice seems to scrape off a lot easier and bird s*** washes off a lot easier.
Its effective for about a year, and then reapplication is a lot quicker 2nd time round.
DoDo Juice Supernatural Glass Coating
This uses covalent nanotech, not sure what the difference is to G1. Similar prep process, to above. However only requires 1 application but you have to keep working a small area at a time until it hazes, the recommendation about using a waffle cloth is worthwhile as it removes the residue very cleanly. This then needs to cure for 2-3 hours. With this and G1 I leave it garaged overnight to make sure no moisture gets on it.
This shows how well it works

And this one that seems to show that DoDo Juice last longer, however I found that G1 actually worked better for longer on the road in th rain despite what this video show.

I feel the result is well worth while.
Conclusion
They both do a great job rain beads and runs off nicely make use of wipers much less.
Both of them give you a super clear windscreen, this is due to the prep work but it stays like this for an amazing long time.
I've used both over the last couple of years and on my recently acquired Z4 I've gone for the G1.
I found the G1 beads and runs off at lower speeds than DoDo Juice for longer in the real world.
G1 is nearly twice the cost of DoDo Juice, but I feel that its worth it,
The two photos showing the screen of my Z a month after applying the G1, I'm playing the hose across the tope of the screen and you can see how the water is clearing away with bits of screen still dry despite the quantity of water going on.
Hope thats of some help to people who are looking at these coatings.
