[Boatanchors] Rejuvenating old hard rubber parts

Glycerin works too.  Just paint it on with a brush and do it several times.

I'd like to thank whoever it was who suggested soaking in 
silicone. 

Fiddling with an old RCA WA-44C audio generator, I found the rubber part 
that engages the tuning dial hard and shrunken to the point it didn't 
work. 

After a day in hardware store silicone spray lubricant, it's soft and 
apparently back to its original size.
