With all due respect to your preference for having people answer your question fully, expressing all the nuances and perhaps personal preferences—well, you might just lose out on some important issues, which take a bit of time to describe. Like "permeability", for example. You might find significant differences between PET and HDPE plastics, not to mention the issue you did not ask about, of different closures, liners in them or not etc. Use the wrong one for longer storage of some film developers and your batch of best negatives gets ruined, while the fixer is still ok.
Gerald is well respected, on this forum, for his depth of knowledge of chemistry, and he, like others, have contributed, many times, to the treasure trove of APUG wisdom. I am in awe of the time and personal dedication he puts into answering complex issues. Except for some highly contentious discussions, you do not see people reposting such important detail every time a question gets asked, because they've already done it, usually just once, in the past. The repeats, on the other hand, are often more trivial and sometimes factually incorrect, as not the usually most careful folks tend to reply. Looking for that great thread on a question may take 5 minutes, but it rewards one with far more knowledge than you'd get from your own thread unless yours is the first, or one of the best threads.
Indeed, some of the better threads start not with a question, but with a list of references to other threads that have already answered a similar question, then pointing out what it was that had not been addressed fully, previously.
Good luck finding a bottle.
