Buttercut works well, though it does have a unique smell when heat gets to it. I get hungry using it.
The most oft-mentioned tapping compound is Castrol's "Moly-Dee". It's pricey but is the one tapping compound that performs when all others fail. I've only used it "at work", and it does live up to the billing on the toughest Inconels, titanium alloys, etc.
