No this is not post about my hand can't reach in corners :D



I was detailing my friend's corvette c5 last sunday. Roof was removed. It was around 7pm after sunset and cool temperature around 60s. I was cleaning rear windshield from outside and inside. We noticed white ( semi opaque) circles ( 1 inch to 2 inch diameter) on windshield. Interestingly they were in pattern, almost equally spaced and not in random positions. I tried EO 20/20 ( inside only) , Stone's Invisible glass ( outside only) and Autoglym glass polish ( outside only), it wont go away.



I remember very well I didnt see those circles when I washed, polish and waxed car in evening ( in sunlight). Next day also I checked car I didnt see circles.



Has anybody seen this before ? Can it be a reaction to cold air ?

Any advise to remove them ? So far, I suggested my friend to turn on heater if it occurs again.
 
Thats normal....its the glass, theres nothing you can do about it! I noticed it on my brothers Vette and the dealer said it was normal.
 
I'm pretty sure it's the material in the glass to keep it from totally shattering upon impact. Have seen this on other marques as well.
 
Interestingly, you can see these spots on just about any window with some polarized glasses. I'll sometimes comment on them and forget others can't see them. It's like some sort of x-ray vision:cool: .
 
Polarized sunglasses REALLY make them pop out! You see them without polarized filters when the sun's angle naturally creates a nearly polarized ray of light.
 
Hmmm...that's probably the purpose of those Ambervision like shades Megs detailers wear.. I guess the polarized lenses make the micromarring pop out easier?

My Revos and Maui Jims have this effect something fierce. I also noticed (OT) that a freshly detailed sled looks GREAT through polarized shades.
