What's wrong with my windows? Are they damaged by detailer?
Discussion
So I had a ceramic coating applied to my car by a detailer, but the coating was too thick on the windows and causing some glare.
I had a second detailer remove the coating, (he used something similar to a rotary polisher) but since then the windows have not performed the same as before the ceramic coating was applied.
When driving in the wet, water on the windscreen gets smudged by the wipers, and the wipers also shake as if they are struggling to move across the windscreen, almost as if the surface isn't smooth enough for them to operate properly (new wiper blades didn't make a difference).
The side windows also don't cleanly dispel water like they did before, water droplets just accumulate on the window so visibility when driving in the wet has worsened.
Did the second detailer scratch up the glass so it is no longer a smooth surface?
I'm not sure what steps to take to fix this. I just want my car to be how it was before any of these people touched it.

I would try claying, followed by a glass polish a few times.

New wipers, the original coater may have put a layer on the blades
It’ll be worth giving your glass a tborough clean too, when I had my screen replaced there was still glue residue which was only visible when wet or in low sunlight, I used IPA, clay & a glass polish (Soft 99 Glaco glass compound) & it’s clean as a whistle
What glass coating was originally applied?

Hate the stuff. You shouldn’t need anything on windows but new wiper blades every few years and use stuff like bilt hamber trace less to clean them and the blades.
Any coating or treatment seems to always leave a mark where the wiper stops just off centre of the screen.
This. In all my motoring career, I’ve only ever used good wiper blades, good screen wash (Decosol) and very occasionally given the glass and blades a clean with meths if something apocalyptic has got onto them.Any coating or treatment seems to always leave a mark where the wiper stops just off centre of the screen.

Some of the professional grades of ceramic coating need sanding off if something has gone wrong with the application, a polish won't be enough.
So in that case would the problem be that some of the ceramic still remains, but not as a smooth surface. but the windows underneath are undamaged? zsdom said:

I already changed the wipers, I didn't make a difference.It’ll be worth giving your glass a tborough clean too, when I had my screen replaced there was still glue residue which was only visible when wet or in low sunlight, I used IPA, clay & a glass polish (Soft 99 Glaco glass compound) & it’s clean as a whistle

I'm not sure if a different coating was used on the glass than on the paintwork, but I believe it was called Cquartz

I’d be finding out if they have PLI & look to claim for a new screen, some coatings need sanding off & polishing, no chance to do that well on glass
A paintwork coating adds a few microns of thickness on top of your lacquer which is why you see leftover product crystalise whereas a glass coating is different & more like a wax & will degrade over a shorter time

Ah, if they’ve used Carpro Cquartz, it specifically says not for the windscreen https://carpro.global/catalog/cquartz-lite/

If that's the case then what is exactly wrong with the glass? I’d be finding out if they have PLI & look to claim for a new screen, some coatings need sanding off & polishing, no chance to do that well on glass

Take it back to the original detailer and ask them to remove the coating - this will typically involve cerium oxide glass polish used via a dual action polisher, or by hand if they want a proper workout!
Cheers,

Which almost always will change the optics of the glass.Cheers,
