I have been using a lutan F mitxure for my tan. My question is, on a deer hid recently finished it had a few brown spots... I am wondering if I didn't shave it thin enough? Also I have been told that I can use the same Lutan F mixture for several skins just keep the PH between 3 and 4? any comments would be helpful. Thanks

No point In wasting anything..the stuff Is expensive enough?
Lutan-f is not reusable. You mix according to weight or volume of skins, all the tanning agent is consumed during the tanning process if you use the correct amount to begin with.

Do not reuse the Lutan F tanning solution. If it's at the correct PH of 4.0 - it will have been depeleted after the first use. Any other skins you add to it later will definitely have brown spots - which indicate untanned areas. Actually you're lucky if the whole skin or cape doesnt look brown.
Max,
The gang is right, don't re-use. One thing that wasn't mentioned that would be worst than brown spots is that your next cape would probably slip due to poor tanning/ PH etc. Also I'm wondering if your brown spots (if you're talking about on the hide side and not the hair side) is actually blood soaked in the hide. Often if the hide was impregnated with blood from the trauma of a rifle bullet, it will show up as brown spots when it's tanned if you don't get the blood out prior. There are different blood removal chemicals offered by all the taxidermy supply companies to alleviate this problem.
