Roland,
The coach is old and very nice, it has been stored inside and all, but let me tell you about the space suit problem....
After the Mercury and Gemini programs, the suits were obsoleted.
So, NASA offered them to museums with the case that they be kept in controlled cabinets. They were, but a couple of years ago, conservators and curators saw that they were coming apart and panicked. They believed that their "controlled atmosphere" just might not be. It was not that. Investigation revealed that the adhesives that they used were aging out. There was nothing that could be done. It turns out to be the case with most all elastomers (rubber stuff). If just ages out without any help from the outside at all.
This is true of lots of stuff like tires and belts and brake hoses and window seals. Trust me, with a coach the age of mine, it has taken a toll.
