“This stuff is great. I' ve battled rain rot on one of my horses for years. All I could do was keep it at bay. Tried this product last summer and in 4 days, the rain rot was completely gone. We've had a very wet Spring in western NC this year and it came again, but I knew what to do. 4 days, cured again. As long as I tend horses, I'll never be without this product. It's in a mineral oil base instead of water so it soaks into the skin and stays. Shake it really well before and during use. Apply as much as the hair will hold.”
