First of all: I am not a taxidermist, just a hobbyist. Many years ago I used a kit to mount a squirrel with satisfactory results. I am working on my first raccoon. I plan to make him into a wall hanging, with flattened head, and body & tail turned into a rug. I have skinned him out, did a preliminary fleshing to remove some of the extra fat, then bagged & froze him. I am waiting to get all my materials & tools together before I thaw him. My question is this: Do I do a degreasing soak (with Dawn) before I flesh? After the fleshing is done I plan to use Borax to dry preserve him. Footnote: I was not planning on taking the raccoon when I did, but he was doing some property damage and he had to go. I currently have a deer shoulder mount being done by a professional taxidermist, and cannot afford to get another critter done at this time. The raccoon in question has a lush almost black pelt and I hated to waste it.
