After various standard misadventures I finally got the new window in at the bunkhouse. Literally put in the last screw and my drill's battery pack tapped the upper window section. Sure as can be, I must have caught it just right, put a crack in the outer pane. Of course it's a single hung window, upper portion not built to move or be taken out
Ahh well, time to see if they're right that rain-x windshield repair liquid can be used on regular Windows [emoji5]
