The sofa saga continued with random flying visits from Mr. Owner until the plaster and sanding was complete. He then used the 7 year old paint to touch up the walls and some random white paint I found to touch up the ceiling.
No - the entire porch was not recoated. But the walls really aren't noticeable, the ceiling is a little if you're looking for it (and walking thought the porch with your head up!) and, well, by then, we were just anxious to have the saga behind us!
