I have a couple of questions about this product Dan Rinehart's Tanning Cream and if anyone would be willing to answer me or give me some insight with this I would be extremely grateful! 1. Is this tanning cream more like a preservative or a tan? 2. Does this cream make a pelt into leather that can be used for a dry tan? 3. Can you soften up the leather (if it classifies as a tan) using sandpaper? 4. Once the pelt dries with the cream on it can it be rehydrated with water?
