Hey Jarred, if you have a raw skin then you are going to want to size and trim that puppy to fit your body. The best way is with a stuffed dutctape dummy (Bovine13"s latest shows excellent examples of this). I have never painted a raw skin before, but I have painted a mask. You want to make sure to clean the surface (again, a seasoned painter will know better than I) of any releae agents that may be on there. Hope that helps
