Grease works fine if it's applied correctly and is the right stuff. I still have a tube of Bosch points grease. It's a long-fiber grease that one puts behind the rubbing block so it's drawn onto the cam as it rotates. Good stuff. It has worked well for me for many years. I also use it on Lucas magneto rubbing blocks. There was a British version I had before that which was even stickier but I can't remember the name just now, same people that made rubber grease for Lockheed natural-rubber, wheel-cylinder cups. Maybe it was their brand, yellow and black tube. In any case, it would probably take some hunting to fine a source for either.
