TOF's got it in regards to bear oil crawling or running. When I rendered my bear fat I used a very high heat and I think that's why I got such nice 'shortening' from it. Too, I used only outside fat. The inside fat is what contains the most oil.
; One of the local loggers, a shooter as well, told me marmot fat was the best water proofer there was. I promptly climbed Hudson's Bay Mountain and shot a few, gutted and skinned them then saved the inside fat, handfulls from each marmot (mid fall & fat) in plastic bags, donned my "Trapper nelson" pack and climbed back down the mountain. The Marmot's were very tasty, but the fat - WOW! It is the oiliest, slickest, most water proofing 'product' I every handled. I used a low heat to render it out and it lasted several years for shooting and boot water proofing. The "Logger' later told me he stopped rendering it out and just thaws out enough fat to do his boots when they need it, rubbing the fat into his boots. For this, it works better than Dubbin, Mink Oil, Sno Seal or Paraffin White Gas. Incredible stuff. To remove it from your hands, you have to wash them in dish detergent 2 or 3 times. It is slipprier than LeHighValley Lube. It also shot well in my .58 as a patch lube.
