What;s a good way to somewhat repair window glass that has "bullseye damage" - a crater about 1 inch in diamter with a small hole in the center that goes all the way through the glass. The glass is not laminated. The windows is an inexpensive aluminum model from the 1960's. The pane is about 3 ft x 4 ft, so I don't want to replace it.
I don't expect the repair to be invisible, I just want an improvement over the current situation.
The auto windshield repair kits, I've seen are only for smaller areas.
