Try claying and see if it helps.

Indeed!! Tried and tested!! Works Wonders!

Similar, but good one heavy rain or big droplets.
Light showers still need the wipers.
Works as advertised.

Yar meh, did you over coat the screen?
I don't have the said symptoms wo.

It says you should let it dry for 10-15 minutes, and ensure 1 day of sunlight or dry area until coating is set.

I applied it last year October. Still beading and no mist as experienced.

Wax is a sacrificial layer and serve no cleaning agents.
There are products out there which are AIO (All in one) but even those are very very mild cleaning agents.

It would take sand blasting or sand papers to grind away paint

So to echo V429's reply, answer is no too.

Yes! Applied this last year and still have the same beading effect until now!
Actually a waste for such a big bottle that lasts so long!

Yes, I am very surprised myself.

I think the important point to note is:-
3. After drying for 5-10 minutes, wipe it off with a dry, clean towel, afterward dry for more than 12 hours, in order to make the coating adhere firmly to the windshield

And also probably a ph balance car shampoo

Haha, I used MF towel also with both being dry. I think the key is the 12 hour curing.
I was lucky in a sense that I applied that in the morning and had no rain till the next day (car kept in car porch).

So curing is important I guess. Did that to both my cars (wife and I).

Haha ya of course! It beads but with Rain fall in Malaysia, we still need wipers.
