They did an awesome job on that aircraft, it literally looks better than when it rolled off the assembly line. I went another time and talked for a while with a docent who had worked as a mechanic on B-29's sometime between WWII and Korea, it was very cool to stand there with some living history next to the machines he worked on "way back in the day".
