I need to replace a window courtesy of a ping-pong paddle that "somehow" went flying. It's old so replacing the pane is straightforward but I was thinking maybe I'd use plastic instead to make this the last time I have to repair this one. I haven't compared pricing but it looks like the plexiglass is easier to work with. What I'm worried about is that it will look different than the other panes. Has anyone done a swap like this an can offer some experience or advice?
