Re: Filling cracks in wavy glass instead of replacing?
The difference between auto glass and a window pane is that auto glass is laminated. A crack in one side of the lamination isn't going to affect the integrity of the whole, whereas a crack in a window pane will continue to crack, if not shatter when you attempt to clean out the crack and fill it with resin.
Since you don't have too much to lose you can try the window repair kit. If you have to replace it, you can get reproduction wavy glass.
