Don't laugh, but I use this product on my horses pink nose. This time of year his nose usually sunburns and peels terribly despite my best efforts. But your black Zinka colored nosecoat completely blocks out the sun and his nose looks great (except now it's black :-)
I will take a picture with my phone next time I am at the barn and send it to you. I only wish it came in a larger size since he has a lot of nose to cover every day. Thank you the black Zinka saved my horses nose.
