I have to disagree with excalibur43. If done right I think a home tan is very close to a commercial tan, if you have a fleshing wheel to shave the skin. I tan pretty much everything in my shop, which gives me more control of product and finish times. My capes are thin, workable and evenly shaven, plus the eyes and face areas are shaved thin. When you get a commercial cape tanned you still need to thin the face.
A home tan will last just as long as a commercial tan!

I use Formic acid for my pickle and then either Mckenzie or Liqua tan. And your deer should still be ok.
