I have used the crap, it will leave a musky almost rotten smell to the hide. I did several heads with it a few years back and man the stick was bad!! I think I can flesh as good as anyone and I know the hides were thin, yet as they dried the musky almost rotten mildew smell arose and it never went away. Two years later I had to replace three of the capes, they still had that stink. You must also think about this, JRTC may have a 4.5pH but it has food preservatives in it, these are what are normally found in Cereals BTH, BHA, when you read up on these you will find they will not perserve meats. These were never meant for long term storage either!! Check out the selflife of those preservatives!!
