It's probabley just water with a gelling agent or it is the gelling agent you add to the water .In essence water with a gelling agent added in is KY jelley ,in kind of a medical form .It's sold as "poly water" to lubricate wires on a long pull or pump down a well to hyrafrac it .Gelled water is just a friction reducer .
If that is in fact what it is the stuff evaporates just like water and leaves no trace .Under certain conditions like cutting near a river or something it might have some merit .Otherwise I personally think not ,an opinion .
