After readin' all this sage advice, tell ya whut I'm a gonna do--I'm a
gonna git me some 6X6 tubes from the nearby farm store  & fill
em up with freon 22 ( that's a mighty big mollycule ) an see how they stand
up.Course it's just a fuselage on gear
brrite now, so I'm not risking my glutes, but should make for an interesting
experiment on the diffusion of large molecules thru not so porus membranes.. 
check back in a year or so & I'll let you know.
