Hello, I am currently considering making an anti-coyote measure, which is meant to stick to calf hide. I already have the active ingredient that is meant for the coyote. But a problem I have incurred is, that obviously for the substance to be a success, it must also be economically viable both in terms of work hours "lost" and cost of the actual product. So if the substance is washed away every time it rains and it has to be reapplied again it would be quite time consuming and costly. Therefore, I am wondering if any of you know any substances liquid or slimey that can stick to calf hide even in the rain? The more common an ingredient, the better.
