I do about 20 deer, and other mammals throughout the year. I have a different day job. Anyhow, ive always used paint on tans, knoblochs. I love and my customers love the results i get. Anyhow is it pressurized or something? Does it improve stretch or is it a marketing scheme? Im not dropping a ton of money for something I dont need. Dropped that on a flesher a couple years ago, Lol.
