  1. All my windows are painted shut in my 1930 bungalow home. Your video was very informative, however nothing was mention about the possibility of the paint containing lead. What would one do in that situation?

  2. One thing that I do is spray WD-40 along the edges to get into the groves to help the window slide up and down I also scrape the paint off the slides and finish with a steel wool to get the paint off and smooth it down for easy moving of the window. Takes time but the result is an easy sliding window.
