I have lots of bike lubes around the house and usually try them first. A waxy chain lube like something from Finish Line would likely spray on wet and then set up once it dribbled down to the remote parts of the cable.� Worth a try.

Just wondering what you all think is the best lubricant for a squeaky

(maybe not the right choice), lightweight oil (ehh...) or some super secret
only sold on TV lube with PTFE or Molybdenum.� I know my old man would have
pulled that cable out the dust cap and slathered it with white lithium but
I wonder how much would actually stay on it by the time it was fully in
place.� Just wondering if anyone has any other thoughts.
