When i was driving through the snow, my right windshield wiper must of broken off from ice or something. So in the midst of highway windshield almost falls off. I take the windshield off to prevent it from flying off the car and what it did is only end up scratching the windshield. Now the windshield has a bump of a long scratch following the trail marks of a windshield wiper. Is there anything i can do to repair this without paying an arm and a leg? thank you.
