<VV> zipper lube

[judynrandy at comcast.net]

Since "top down" season is upon us, I have had mine down a couple of times this spring.  This was a shakedown cruise for a new top from the corvair 
ranch.  A while back, someone mentioned something for lubing the zipper.  The top worked great except for the extremely difficult time I had trying to zip 
up the back window.  I'm tempted to just leave it zipped.  Anyway, I believe someone mentioned "beeswax."  If so, where does one buy it?  And, would 
wax from an unused toilet bowl seal work as well?  Thoughts and opinions welcome.     Thanks.
