I've had my windshield ceramic coated with
Stoner / Invisible Glass product a few months back. Water beads perfectly off it (similar to fresh RainX, but supposed to last way longer) with zero windshield wiper (Michelin) chatter.
I did wipe-off and polished it as soon as applied coating flashed, and left the wipers off the windshield overnight to allow everything to fully cure.
What product brand did they use?
Do you have some of it on hand to polish/re-apply as necessary?
Wiper blades are unlikely to be your problem.
The more likely culprit is uneven application of ceramic coating to the glass.
The only tricky thing about ceramic and graphene coatings is that they evaporate and harden in 1-10 minutes (varies with weather and product), and require instant leveling and polishing before they harden into a wavy pattern. In a large scale commercial shop that makes money from volume of cars processed, it's easy to miss the narrow window (pun intended) before ceramic coating hardens into a wavy surface pattern in which it was applied, with high spots catching the wipers as they pass.
Or, if they dropped the wiper blades onto the glass before coating fully hardened - that will create a "step" on which blade will "catch" from there on out.
Sorry, it's the opposite.
Ceramic coating fills in unevenness in the glass surface and seals them. Thus reducing surface friction and allowing water to bead / roll-off with minimal effort.
There are dozens of products out there that strive to achieve this result. Most work really well. Few last longer than the others.
Totally agree on the first step - clean the wipers.
If they are covered in gunk, they will catch over any surface!
That would not be a problem. In fact, some coatings (but not Stoner) call for the ceramic fluid to be applied to the blades as well.
