Now is the time to think about those old, cold, drafty windows. If you have windows that are in need of a little weatherproofing , you may want to think about V-Bronze. I'ts also known as spring bronze. The pic to the left describes how it is done. It's not hard to do. A little boring maybe, but not hard. I recommend a nice vodka martini while working. Just don't hit your thumb with the hammer.
