First spread glazing compund along the lip and then spent several minutes washing it off my hands. Then I dropped the glass pane... gently into the opening. Pressed firmly into place, and added points. And finally scraped off the excess glazing.
Yes that's Miss Sophie wanting to come back inside.
High end options I chose: 1) a coat of oil based primer before glazing. this will keep the wood from wicking all the moisture out of the glazing, which explains why ours was so dry and brittle.
2) our exterior doors have stops, or fancy trim pieces that get nailed to the interior side of the window. this creates a stronger hold for the door window but they failed to add points, which I added.
3) used longer finishing nails to hold the stops in place for a better hold.
