Any solution will have limitations, because many surfaces that appear in nature are fractal and actually do not have a welldefined area (the smaller the scale you look at the more pockets you find and the bigger the area appears) Choosing a "paint" of a given viscosity effectively chooses a scale but the choice is arbitrary. If you know why you want to measure the "surface area" this may give you a hint how to do it. RD
