Goat skin is pretty tough. If it gets dirty or dusty, wipe it off with a barely damp lint free cloth. Other than that, do you have any specific questions?
I've never used shining Monkey, but have used Appleguard with great results. The lotion works well, however the rain & spray protectant .. I'd recommend spraying from a good distance.. and just lightly "dusting" it on your BV.
