My new car (only a month old) has scratches on the windshield from grit in a squeegee. The scratches can't be felt with a fingernail, so they seem to be candidates for cerium oxide polishing. Unfortunately the scratches are all half the width of the windshield, and both halves have these scratches - so I'm gonna wind up polishing about 60% of the entire surface of the glass, it's not just one or two spots.
I'd like to hear from someone who has used this material; specifically, I'm worried about clouding. At the moment I have a usable, but annoying piece of glass; I don't want to make things worse :)
I'm willing to invest a day's work polishing this if it will save me $350 for a new windshield.
