Ok.... Where to start. I began using dp. It's how I was taught but I've mounted a some lifesize that were tanned and liked it. My thing is the measurements rarely line up with the carcass measurements I took. Always smaller, so it was suggested to use stop rot and dp on my smaller mammals. Works out good, hardly any shrinkage. I've used DP on the deer I was doing and love how it mounts up easily. The size is right along with being able to position things easily. Still I want to do the best I can so I got some Krowtann wt formula. Followed directions perfectly and it's 2 inches smaller in the neck. Now the tan looks good, it's got a wet dishrag looseness but it just won't fit the 18 inch form It's measuring 16. I measured it tight behind the ears and I mean tight on the carcass. Now my guess is its not shaved correctly perhaps or I'm suppose to go by after tan measurements. My argument with those things are, if I can dp it at the thinness it is and get the detail, look, fall in place etc and it dry well then why would it need to be thinner with tanning? I spent 4 days tanning this deer and am just upset I can't use it on the form I know it fit raw. If it is measured after tanning then it's not true to what it was brought in. Am I completely wrong? I'm so frustrated. I want to tan but its just not working out for me. In my opinion a cape should fit a form easily for back stacking etc to create a smooth mount. Idk. Maybe I've never seen a properly thinned hide to know but I'm just really frustrated. I have a mini flesher and in no way can I afford a shaver right now. But like I said I just need to understand if the tan is wrong or If they don't go back to the right size, if so why do it. If the cape is properly thinned for dp why does it have to go thinner for tan? Just want the best work possible.
