What's that stuff on my windshield?

Those dots are "supposed" to provide some shade, but it doesn't work very well. It serves no other purpose, so it's perfectly OK to cover them up.

 

They actually are designed purely for aesthetics, to make the rearview mirror look better from the outside. Not for shade. Cover em up.

 

Well, -I- think it's for glare reduction when you look in the mirror . But to each his own interpretation of function. It's safe to put the tinting over it.

 

Ask a windshield installer what its for. Its not for glare reduction, its simply for appearances sake.

Simply believing something is true does not make it so

 

Remember though the tint might not stick as well in the area with the dots. It is not a smooth surface so it might look kinda funky from the outside of the car.

 

I thought it is for glare reduction because the two shades (driver and passenger) doesn't cover that middle part when then sun is hitting the windshield. It has helped me before in this situation.

 

I thought it was there to reduce glare on the MFD.

 

The true purpose for those dots is to catch lint from towels so it isn't left in your safety area of your field of vision after you clean the inside of the window.

 

Just to make you crazy LOL

 

They are for glare reduction. Here is a link to an aftermarket version called Suntamer, so you can add more if you want!

"You'll see overhead signs and changing traffic lights, but you won't be blinded by the glare of the sun sneaking between your visors."

 

Classic Prius lacked that glare reduction feature. I had to add my own

 

I've been told that most modern windshields contains a reflective layer to stop heat (and/or UV) to enter the car. The problem is that this layer also blocks signals (doohickeys for automatic toll booths and to some extent GPS signals).

The "shaded" area around the mirror does not have this layer, and thus will not block these signals. And it's very parctical to put a GPS antenna or other stuff behind mirror, out of view.

I had a strip put across top of windshield, surprisingly the tint film stuck and it looks OK.

I agree with Michgal007, the dots behind mirror provide shade for the space between sun visors.

They cut around that on my tint job. The tint goes right up to the outer edge of the dots.
