Mentioned in my OP, already used but didn't help much.

Rain-X made mine chatter like crazy. I had to remove it, then it stopped.

How did you remove the Rain-X?

Bosch Excel + wipers are the go to solution for wiper chatter issues. One of the best wipers out there.

Does it fit or needs adapter to make it fit? Thanks.

Just to give everyone a quick update, I cleaned the windshield with thinner last week. It seemed worked and helped chattering a bit. Yesterday during tropical storm, wipers started chatter again and this time was bad. i had enough and took it to dealer immediately. Technician saw the chattering and took the car in. 3 hours later got phone call from service manager said the technician replaced blades but didn't fix the issue, adjust wiper arms didn't fix it, replaced the arms didn't fix it. Now, they think the motor is bad and need to order parts. Hopefully replacing the motor will fix the issue.

At 40k, I just experienced this for the first time the other day. It only did it on the delay/intermittent setting. After I turned the car off and back on it went away.

Don't think it has anything to do with window film.
