Ed, a reaction with the layer of green paint is a good explanation. Using less alcohol might be helpful.
How do you mix alcohol and water? I did never find a perfect formula. Too much water and it stands in drops on gloss paint (nasty black spots) and too much alcohol and the paint is dissolved (may ruin fine print and lines). It looks like it depends also on the kind of paint. e.g. dull Tamiya is very sensitive to alcohol while Walthers 40' boxcars have a very glossy but robust surface and need a lot of alcohol or the water stays in drops on the surface.
