I had it happened to me a few times. Especially when i was in
a hurry applying the coating. I believe the windshield wipers might skip/shudder because of the coating none-uniformity. You either had high and low spots on the windshield. You could try to polish the windshield and reapply in a more uniform fashion (cross-hatch pattern). |

No issues with windshield wipers skipping on a ceramic coated windshield on two cars. I do have Exoshield applied to the windshield and then ceramic on top of that.

Sure, wiper has more variance but it is more compliance. Also, rhe wiper will skip in various area if it is due to the wiper. The problem usually happen in the same areas of the windshield. I am just giving the OP my experiences. It actually drove me crazy and changed several wipers and got the same result. |

Call me crazy but I have ceramic on my car and wheels but never felt the need to do the windshield.
Does it really make that big a difference and do you also put it on the side and rear glass?? |

Yes, using window coating with Silicon Dioxide (SiO2) will help with water beading off the windshield. Basically they are the new "Rain-X". |

Glass coatings with Silicon Dioxide (SiO2) usually crystal clear after applied. Based on my personal experiences, it makes a big difference when the rain isn't that hard and I don't like to have the wiper dragging across the windshield. When the rain is heavier, the water mostly bead off the glass. It is also last much longer than the typical materials like Rain-X. |

My buddy is using Gyeon Product and also happy with it. I am sure there are many products out there and they're most likely performing equally OK. Just like Paint Coatings, prepping and applying will determine how well the coat will work and last. |

I guess it is more user's errors as I didn't apply evenly and had similar issues as the OP. Now, I am more careful and taking my times to ensure even coverage. Plus don't apply to hot windshield (or out in the sun).
Also, it is bit harder to remove (probably indicates that the coating is bonding well) but my buddy showed me a trick where I slightly mist the towel and the excess coating come right off. Check out Esoteric, one of my favorite cars care/detailing Channel. |

I am glad you eliminated the issue without having to do over. Yes, I forgot to mention that coating the wiper blades help. However, I noticed that the blades became a bit too slippery and sometimes not effective at wiping off contamination. IMHO, the rubber blades need a bit of "fiction" to effectively clean the windshield.

I coated my shower doors 3 years ago and the coating also helps tremendously. I'll wipe them down every few months and that's about it. |

The biggest advantage is actual visibility through the glass. With the coating, the glass doesn't get flooded with fluttering water film, but all the rain drops condense into a small, individual droplets. This will provide significantly better visibility through every window at any precipitation intensity and/or road speed. Wiper intensity requirement is also reduced but that is a subjective variable.
Like most ceramic paint coatings, window coatings are tacky. If you polish a paint or glass and then wipe it with a dry towel, it is usually smoother then after coating. This increased interface friction is what induces wiper judder. As the interface friction has many variables like wiping angle, rubber friction, glass/coating friction, wetting agents, wiper arm speed, surface contamination and so on, it is not a one solution fits all scenario. You cant modify coating friction in non destructive way, but you can modify wiper friction in different ways. New wipers are always smoother in the beginning of their life, but you can also coat them with the coating product as you have done. I personally prefer Carpro PERL to decrease interface friction. Not only does it do a great job to reduce friction, but it also rejuvinates the rubber and makes it more pliable. I have a feeling that coatings do the opposite and benefits are short lived. Just make sure you dont put paint ceramics on your windshield unless it is clearly stated to be compatible. |

Some glass coatings will cause skipping in some environments. There is a tradeoff in the chemistry between slickness and durability for a glass coating. The more durable and hydrophobic glass a coating tends to be, the tackier it is in general. That tackiness contributes to skipping in some situations. My wipers skip sometimes with the coating I used but mostly when dry or there is very little moisture on the windshield. There are glass coatings that won't do this at all, but they tend to be less durable on the whole or at least will lose that slickness over time. You may or may not have luck coating the blade.
