Youngest son just got his first (used) car. It seems to be working well after his first month of ownership but it has an annoying visible whitish arc about 1/16" wide on the passenger side of the windshield caused by a broken wiper blade assembly which was dragging metal over the glass. Said blade was on the car when he got it. (Why some people will drive a car and ignore stuff like a busted wiper blade is what separates us type of folks from the rest of the world.)
I remember when I was a kid (circa 1950) there used to be traveling glass polishers who'd make the rounds of car dealerships and spruce up the used car's windshields on the spot by polishing out scratches like the one on son's new (to him) car. I expect those guys have gone the way of the dodo by now.
IIRC they used cerium oxide with a felt buffing wheel in a drill motor to work their magic.
I'd like to help my son fix that scratched line, it has insignificant depth, and it's out of the passenger's straight line of vision, so a perfect surface isn't required. Can someone here confirm that cerium oxide is the the stuff to use and suggest a good place to buy a small quantity and some suitable buffing wheels. Or, tell me what's being used for polishing glass nowadays.
Thanks guys,
Jeff
