same problem - i checked with some glass shops til i found a local shop that did polishing - he looked at it and said no! - i could just barely feel the scratch with my nail but that was enough - they do sell polishing kits on the web (google search glass scratch repair) but they are the same kits that the glass shop uses with polymers etc... besides the glass shop told me even if they could repair it they would charge more than it would be to have them replace the w/shield with labor, parts, etc... appx 225.00 installed price for a NEW windshield in a 70 fastback mustang
