I think freon is incredibly inert, that's why it's used.
Since there are so many ways to protect the contents of the message the freon topic is not all that interesting. It would be mildly amusing if there were a way to detect that freon had been used on a piece of paper. I would guess that it could be done by either finding an "ink" that was dissolved by freon or some other material that would sit happily in place until lifted and dispersed.

Freon seems to be ( or have been ) used mostly for degreasing.
It was, now it is being phased out because freon is damaging to the ozone layer. Try locating some R-12 for your automotive a/c system, time was you could buy little 12 oz bottles in do-it-yourself kits at every corner parts store. Reese
