I've got a 500g tin of Comma Copper Ease, the size of a syrup tin, that I'm not even sure they make any more, it's easily about 15 years old and is still about a quarter full. It's good stuff and pretty much essential if you're putting titanium bits together, both with other titanium bits and with non-titanium. The price sticker has long since worn off but I think it cost about a fiver from a local car spares shop.
