Linda, I went and checked Cat's thread. Wow. I had no idea that was going on.
Good luck on your windows Bubbles, I know that is quite an expense! We have a window that a bullet ricocheted off of but we patched it... until it starts getting moisture between the double panes, then we'll look at replacing. The problem is the manufacturer went out of business so we're looking at custom I guess! Now way would I want to replace them all, even in the one room would be an expense!!
