Yea,I saw that low pressure out-gassing as well, but noted it
disappeared at higher pressures as would be expected. How about the
first science run: http://www.cmdl.noaa.gov/hats/airborne/lace/lace11.html

BTW, the AC in my 2000 Cherokee works great with R134a, and my Wrangler
doesn't need AC since it rarely has a top on in the summer. My kids are
much more important to me than saving a couple of bucks on a recharge or
retrofit.
