What is this stuff on my windows?
I took the leap and removed two of my wooden sash windows to scrape, prime, and repaint while the storm windows are on order. Among the products I purchased was glazing compound, since what was there looked pretty bad, was missing in areas, etc.
As I'm working on the windows, I'm coming across something in some of the joints and in the glazing compound area. It is a soft waxy product, similar in consistency to a bar of soap, but a little softer. What is this stuff? It is light tan in color.
