How do I remove self-inlicted scratches from my windshield?

Dear Tom and Ray:
Ken
RAY: Yes. A large brick.
TOM: Actually, Ken, what you're going to have to do now is take the car to an auto glass place. If the scratches aren't too deep, they might be able to buff them out--that is, remove a thin, outer layer of the glass in order to get rid of the scratches.
RAY: Of course, you should try to avoid using abrasives on your windshield in the future, Ken, because there are only so many times you can buff a windshield. When you start to feel water hitting you in the face, you know you've gone too far. At that point, write to us again, and we'll tell you where to get storm windows that fit the Lexus.
