Gurney Goo is a product that was designed to protect the skin from the extreme elements and then inadvertently became the most versatile, must have product in the medicine cabinet that effectively prevents rash caused by rubbing, sweat, allergy and heat as well as preventing blisters and other forms of skin irritation. By providing a barrier on the skin, the natural ingredients contained in Gurney Goo help to keep nasty things like ticks (cause of Lymes Disease) and leeches from attaching to the areas applied.
