on our contour we see some scratches.. it looks like someone used a diamond to scratch the glass, but looking at the who thing and at the dust on the vehicle at times it is probably the dust particles that are getting caught in the rubber by the window and if its from an abrasive then it will do a number on your glass... i have several on just about each car we had over a period of time..... even on the TV set i guess we just pushed in and wiped the dust off instead of wiping off the glass to get rid of the dust....
the insides of the windows in the garage even have it, looks like someone with a diamond ring went to town on the glass.. guess we did it after i used an emery wheel in the garage to cut something with the dremel tool.....
