Odd smear of stain on glass

[Paulyfe12]

my brasnd new 2013 gti has a strange transparentish clear stain or smear on the glass, after inspecting it im pretty sure its on the outside of the window. I have used window cleaner and I have even tried claying the area. but it doesn't affect the strange thing. Im on the fence about buying a hand cutting and polishing pad and glass restorer from detailers car care, or possibly using that glass restorer with some glass polishing pad. I cant really feel it with my fingers, but it will "catch" a microfiber sometimes. Any ideas?

the polishing pads would be used with a griots polisher

actually, they look likes scratches, can you get scratches inside of glass?

Less likely inside but it can happen. If the MF catches on it then it's outside, but you can't catch it with your finger? Post a pic, maybe someone can ID it.

stupid camera wont focus on the scratch keeps focusing on the reflections. srry dude, but yea it looks like a bunch of scratches, in the shape of a products drip. and yea cant feel it

There was a thread on glass scratches recently, talked about how hard glass is & when it's scratched it's VERY painstaking to removes them. If you do a search you'll probably find it; as i recall it was within the past 2-3 weeks. You may want to check the Meg's forum too, it may have been discussed there rather than here.

In the shape of a drip? Wonder if it's an acid that caused the damage, usually products aren't strong enough to do that unless I'm mistaken.

Hydrofluoric Acid (HF) will definitely
etch/eat-away-at glass. :eek:
