Great! But understand, I'm just doing this for my own regs, so don't spend too much time on it. I mean I'm only going to need about 4 oz. every two years, so if it doesn't work out ROI-wise, I totally understand if you come back and say it just isn't worth your time. Also, it looks like this method of sealing a regulator is already obsolescent and rapidly becoming obsolete, so besides me there may not be much of a market out there. But you're probably in a much better position than me to judge all this, so obviously I leave it up to you.
And as far as fluorinated oil, I'm no chemist, and I sure as heck can't do a reasonable analysis and comparison of the environmental impact of fluorinated oil vs. silicone oil, but as soon as I read the word "fluorinated" all these alarms went off. Reminds me of the time the Fabulous Furry Freak Brothers took their VW minibus to the "Organic Mechanic." Hmmm, do you smell bananas? I guess he replaced all their petroleum-based lubricants with plant-based ones. Worked great until they got stuck in that traffic jam.
At any rate, I appreciate the help you've given me so far, and I've already ordered a 2 oz. syringe of Christolube MCG 111 from Scuba Tools.
