I just bought this jacket - http://www.wilsonsleather.com/product/index.jsp?productId=20452806 The shell is lambskin. It's very soft and has a nice cognac color. I'm trying to figure out how best to care for it without damaging or discoloring the leather: First, what kind of spray or weather/stain protectant should I use? Second, what sort of conditioner should I use, if any, and how often should I apply it? Can anyone provide advice? Thanks!
