I have never painted over dope before, but I am planning to do so very soon. I will be using Vallejo Watercolors. I will thin them down and use my airbrush. Stay tuned to my "Red 13" build and we will see how that works.
That model is now covered in 2 light coats and 1 heavy coat (as per instructions) of LustreKote. Made by Top Flite. It contains Toluene and Butyl-Acetate. I asked my LHS owner and he thinks there should be no problem with water colors. Since I will be airbrushing it will go on thin and dry quickly.
For you, another thing I would make sure of is that the paper is sealed well. Then brush on water colors.
That is my suggestion, it would be an experiment.
