I purchased pen blanks on e-bay that were delivered with a sticky wax coating. How can I remove the wax? Will it effect the stabilization process?

Yes, the wax covering of your blanks will certainly affect the uptake of the Cactus Juice.  The best way to remove it without changing the size of the blank is to submerge them in a pot of boiling water.  The wax will melt and float to the surface, then you can skim it off and remove the blanks.  You will need to get them dry again before stabilizing.  If the blanks are oversized, you can also cut a little bit off of each side and both ends to remove the wax.
