Does it hurt this stuff if it gets frozen? I have tanned a coon a fox and 2 deer capes with it and have never had any trouble. I tanned a L/S coyote a couple weeks ago and its slipping real bad in ithe ears and face. in the pickle 3 days at 1.5, put on the tan and let it set for a day. I then rinsed it and washed it in salt water and some fabric softner and froze for about two weeks. Got it out of freezer last night , thawed and was taking the ear cartlidge out and noticed the slipping. any suggestions? Also just a note this thing was skinned 4 hrs after it was shot, turned and split and brushed on Stoprot. and into the freezer.
