I hated getting rid of my "original" windshield... Sure it was heavily pitted and driving at night or at dusk with it was borderline dangerous, but i eventually had to do it... Replacing the windshield is never the same as the original.. Now with the new windshield "sekurit" i believe, whenever the wiper goes beyond a 45 degree angle from the center of the car the outer most edge of the blade loses contact with the windshield and makes a very sloppy wiping edge.. My conclusion is the windshield they put in was either not shaped properly or not seated properly and the glass was slighty twisted enough to cause this problem... I have replaced the windshield wiper and no fix.. So a few months later after replacing the windshield im going to try another Glass Manufacturer to see if i can get a closer to OEM match or better fit.. picky benz owner
