My windshield was badly scratched from the wipers. Pilkington USA will not ship direct to users any more. I had to go through an installer. I got a quote for $415 for the glass, $50 shipping and $175 labor for installation. BTW, I got a quote from Pilkington in England. They would direct ship but that would cost 436 pounds+ 550 pounds for shipping. They are Triplex brand.
I called Super Glass Windshield Repair. They said they could fix it. The scratch definitely caught your fingernail, which online says cannot be buffed out. Anyway, it cost $150 and it came out perfectly. I also had them polish my Lotus side window which had a bad scratch. That cost $50.
So, for $200, I got both pieces doneand they are scratch free. The only issue with the windshield is a small amount of delamination at the edge which cannot be repaired. It is mostly covered by the gasket though.
So, it was a good experience.
