i use pine sap,rabbit poo,charcoal
but have been adding bees wax to it lately,i like it this way much better
i would think that any sap should work as long as it hardens up
as far as mix ratios go
i just melt some sap,add the other stuff untill i get the consistancy i want
dont worry about making "to much"
just put it on a stick and youll have it when you need it
my last batch made a pitch stick that was 4" in diameter
still using it,its about 1.5" in diameter now
hafted many arrows/blades/ and even a hawk head with it
