Ok, so I tried searching for this, but came up empty handed. I have noticed this for quite a while but am kind of getting curious.

When it gets cooler, like in the evening, i noticed that both my car and my dads car(both 92 celis) have these spots appear on our windows.. I dont know what causes them or anything, but I figured somebody here would know.

Ya, but im wondering what causes this...

Are you talking about tint spots? Usually happens on the back windows?

It happens on the front windows as well....

I think it's the polarization in the windows...

If I recall, that's waht it is...

Mainly happens on windows with a large amount of curvature to them...

Polarisation -- with the sun low, you're getting filtered light, with most of the higher frequencies refracted by the atmosphere (the sunlight must travel through more air to reach your eyes, which filters out the higher frequencies such as blue and violet).

Your windshield also refracts light but does it unevenly, producing the spotty appearance. Look closely and notice the colours.
