im astounded that a manufacturer using cordovan shell from horween is recommending turtle wax on their strops.. good thing they dont prep their strops before they send them out that way. ive never heard of such a thing before.. yes some leathers are waxed during their manufacture.. i think english bridle is such a leather. and i could imagine using wax to repair/alter a strop that needed it, but i dont think turtle wax counts as wax, and i wouldnt use it on leather.
