Has anyone ever had any luck removing a corroded valve from an fx cf bottle? My bottle is leaking and I bought the tool to take the valve off to replace the o-rings but its so badly corroded that I broke the bottle removal tool and I also took it to a shop where they broke their tool trying to take it off. I tried wd 40 penetrant and soaking it in there for an hour, still no luck. I already bought a replacement bottle with a stainless steel valve but I'd still like to repair this one if possible. Any suggestions would be much appreciated
