Excess Marathon Liquid Skin Protectant can be removed before it dries by wiping it with a clean tissue. Once it has dried, unwanted Marathon can be softened with petroleum jelly and removed. It will naturally wear off within 1-3 days as the skin naturally sheds off.
Marathon takes about 60 seconds or less to dry, if you applied a uniform, thin layer of the product. If a thicker layer is applied, longer time is needed to let it dry. Thicker layers may also lead to premature cracking as the product loses flexibility.
