In no way am I knocking Krowtann, and I'm not saying the guys that use it are crazy BUT it didn't work too good for me. I send all my capes out, but I've been tanning small game myself. This is my first attempt at Krowtann, and I followed the directions to a T. I live in a city and I know they put all kinds of crap in the water in the winter so I'm sure it effects my tans. I did 2 gray fox and one came out fine but this is what I got with #2. 50% Is no good IMO. Luckily this was my own and not a customers fox but I wont be taking any more chances.
