I hatetosay it bt if the paint isn't damaged I wouldhave to wonder if it was vandalism.

I mean paint is so easy to key. This looks like something on a broom used to clear the snow or a tool that was supposed to remove some frost but scratched the glass.

Now let's consider the glass.

Safelite uses windshields out of China. I won't use their product even on my beater jeep. However, many insurers insist on them so you are kinda stuck.

So perhaps an innocent attempt to clear the windshield with say a broom out of the shop with metal filings on it.....Would do exactly like Woody suggested with the wiper system. Should not have been able to happen but......

The good news is that if it was a vandal they didn't do your paint. Paint would be far more costly than the glass.

Repairs of the glass will likely give you distortion as Mike in Orange suggested. If it was me, I wouldn't try. Just replace it, but do so with Pilkingtons.
That is the original glass.

I'll wager Safelite didn't use the right urethane sealant system either.

Go for the Pilkington.
Insist on it.
