I just picked up 5 fermonsters for a song and while I've yet to actually use one (will be in two weeks for wine) I've read quite a bit on these O ring problems. I use better bottles and never had an issue. I just needed more vessels. but with all this talk about the O ring issues has anyone thought to just caulk some silicone in there? Surely that's soft enough to be pliable and form a good seal once screwed down, right? Then it's a permanent, sanitizable solution without the need for replacing o rings and struggling to get them in.
