The trick to water shrinking tissue is to use as little water as possible. Spray a fine cloud into the air and waft the part through the mist. Just enough moisture so that the tissue starts to sag.
If you dope the tissue, airbrush on a very light, thinned dry coat. Let that cure until dry to the touch, sand it with fine sandpaper to remove the fuzz and then gradually build it up with more thin coats.
