I have been meaning to report this experience with Stop-Rot. A customer brought a frozen bear to me for prep work and the ears were already thawed. Since it was 100+ degrees, we were very concerned. We injected the ears with a hypodermic needle filled with Stop-Rot and got it back to the freezer. The trip took three hours before the return to the freezer. Last night I finished the prep work. The ears turned very easy. No freezer burn and a side effect that was unanticipated was the Stop-Rot swelled the tissues on the ear to the point that it was nearly pickled! It took a lot of time to inject the ears, but WOW, what a result! Thanks to Whitetail Designer Systems...now go get some for yourself.
