I tried Lanotec A (on a bolt and screw) and mechanically, it seems it is the right stuff
Right viscosity, right stickiness, does not flow out, but it is not solid either.. all this on room temperature.
Now, it remains to be seen how it behaves in the fridge (Andrew already checked on warm temperatures, was OK right?)
And, if it is chemically stable (that means, if it won't oxidise), we have an ideal lubricant for lenses and slow moving gears and bearings, cheap, local product from Oz. The smell is not strong at all, it is even quite nice (to me that is... like new unwashed wool - not surprising, the stuff comes from wool. However I can imagine that some small number of people may find it un-acceptable).
