Felt can be stapled, glued or put in place, but it doesn't offer much protection against moisture.

To repair a broken window seal using a putty knife, you need to remove the old caulk. Wearing eye protection and gloves, carefully pry out the glazing points -- small fasteners that pin the glass into the frame's recess with sharp and pointed edges.
