For what it's worth, I find most glass coatings do or can make wipers chatter.
I always use Pinnacle Black Label Surface Coating. Works great, no chatter. After 30 mph water flies off the windshield.
The other thing I do and educate others on is when it comes to the windshield, because a RUBBER wiper is going to drag over the glass, it's going to micro-abrade anything you put on it off.
It's reality. So instead of looking for a
one-and-done or
set-it-and-forget-it type product, I look for a product that
quick and easy to re-apply.
I already know whatever I put on it is going to wear-off, so I find something that's quick and easy to re-apply.
Make sense?
Then after washing and drying my car, because the Surface Coating is quick and easy to apply - I simply re-apply. It only takes a few mists of product and it spread out and disappears as you wipe it.
Truly a versatile product. I also mist it over all the cars I detail after the initial coating install. It makes rubbery coatings feel slick, smooth and slippery. The stuff is bubba-proof.
FWIW and YMMV
