Hi Peter The range of: 50, 100, 200 cSt Just depends on if you would like it a little thinner or thicker. I have used the 100 cSt for years, it is a little thick, kind of like vegetable oil. a bit thicker than baby or mineral oil.

Ya know, the perfect one to apply without having to dilute or alter at all. Too many viscosity choices here.
