Just so you guys know, Sno Seal is made using 65% bees wax mixed with 35% mineral spirits, which is an old timey bees wax recipe to waterproof leather.
I've used Montana Pitch Blend for quite a long time, prior to that I used Pecard's. I've not had the same issues as you described. The Pecard's would leave a sticky tar residue which I always disliked, but any excess of Pitch Blend would wipe off leaving a dry to the touch finish. The only time I experienced the dry cracking leather was when I made the mistake of leaving leather too close to the stove or fire too often.
