Re: exceptionally soft glass??
My Windshield is getting lot's of chips. I speed past SEMI's because of the rocks they throw up on cars. I seem to get them more, because of sitting so low.
But, I also use to use those fiber cloths on my windshield, after washing the car. But it seemed to leave little fibers on the windshield ....And boy , when I was driving into the sun, it was like I had lint all over the windshield! And these cloths were new, and also washed....So this tells me, the windshield is worse than it really looks like.
So back to white terry rags for me, so that I can see in the direct sun light!
