So I have been searching around for this and not found anything.

In certain sunlight at certain angles I can see uniform spots on my windows and rear hatch glass. The spots are just slightly darker than the glass. Another weird thing about it is that you can't see them at all from the inside of the car no matter what angle you look.

I know people have had problems with grease streaks on their windows but this is definitely not that, these are uniformly placed spots.

So the question is has anyone else seen this? Is it a problem?

I am about to tint my Z so I am wondering if I should try to get this fixed first.

 

yes, they are common problem. Just tint your window.

 

yep. I've had mine since Jan. Now that the sun comes out during the day and I park in the same spot when I look out the window at work my passenger side window has a checker board pattern to it. I guess who cares as long as it doesn't look that way from inside.

 

I always thought it was a result of the UV blocking and the tempered processing of the glass that caused those spots.

 

I think it's normal. I've also noted this and as Aggro_Al said it's probably a part of the design of the glass. I wouldn't worry too much about it.

 

Thanks for the responses! Glad to know I am not alone.

I don't think it's that big of a deal, I will go ahead and get my car tinted. The tint may even get rid of the problem since it will be darker than the spots.

I am getting formula one pinnacle 35 in case anyone is curious.

 

I noticed the same spots on the hatch window. No big deal though as I was able to wash them off from the inside. In other words, clean the windows inside and out. If this is not the case then I have no idea why yours is different then what I had.

 

Do you ware sunglasses/perscription glasses? The polorization of eyeglasses and sunglasses will dot windows due to the contrasting polorization in the tint/glass.

 

^ Your nav screen will do it as well. Tilt your head from side to side with glasses on. You'll be able to black the screen out completely.

 

I didn't notice them until a week ago, when I started wearing my new polarized Ray Ban's. I think it's probably just normal.

 

I was about to say the same thing, wear some polarized glasses and you'll start seeing those spots on almost every car. it's really weird. take off the glasses and you see nothing!

 

I do wear contacts, are they polarized? I took my car to the tint place and that guy saw it too, so unless he was also wearing polarized contacts I doubt that is what is causing it.

I will try taking my contacts out though just to make sure.

 

Yep, just polarization. Pretty much all cars since the mid-90's have had this.

 

Have no fear, that's normal. I think that's the factory tinting, had them on my cars since the 70's.

 

special uv protective glass...

 

Tempered Glass Definition (Scroll Down)

I assume we have tempered glass, here is the relevant info from the definition:

"Spots or blotches may, at times, be visible on tempered glass, especially when viewed through polarizing lenses or in certain types of reflected light. The intensity will vary with lighting conditions and viewing angle. This is caused by the strain pattern induced during the cooling stage, and is not inherently a cause for rejection."

Thanks again for all the responses! Glad to have an answer.

 

Mine looks like a thick net when the light hits it right. Looks kinda cool actually...

I dunno if it's the streaking people are talking about, but it doesnt bother me at all.

 

Yah - I just noticed those little circle patterns on the top part of the hatch window the other day...

 

This post is funny to me because i just had an argument with my g/f about this the other day. I'm driving and I notice the spots and they are very pronounced, I never saw them before. I ask my girlfriend if she ever saw them before and she looks at me like I'm nuts. I tell her to look at the windows there are spots all over them and she gets a concerned look on her face and asks, "what's wrong with you?" So now I'm pointing at them and yelling, "these spots all over here." She is telling me there are no spots and I'm seeing things. I lift my sunglasses up to rub my eyes and, voila! The spots are gone. I then realized it was from my polarized lens in my sunglasses. We had a few good laughs about it.
