Any little bit, short or extra can  throw your
product off. The knobs will either come out sticky and
never  dry or can be rubbery and never harden.

I paid attention to the A and B amounts using the small measuring cups  
supplied, but the knobs ARE slightly sticky.  And, the one that  feels the best is 
bleeding liquid at one small spot in the center of the  knob.  The mix is old, 
but the bottles appeared to have been well  sealed.  I do have some 
additional casting material, and will see if it  makes a difference.
 
Also, one very small air pocket appears on each knob.  I thought I was  
pouring slow enough to let the air escape, but maybe not.  It looks like  the one 
air bubble appears where the mix is first poured.
