I tried something, and it is not working. There was a cool post about 2-3 weeks ago and do not get me wrong. It probably does work nicely but not with all paints. I am working on a Japanese zero, 1:48 from Tamiya. I wanted to do the beat up chipped look. The reference said to apply a silver primer, apply future, apply your top color, wait one hr and use tape to pick off paint. Turns out, I would guess not all paints lay well on future. In this case, I painted the bottom the light grey and that was actually fine, two coats laid on well. I then airbrushed a 1:1 mix of the Modelmaster enamel japanese jungle green. It ran like crazy, even getting under masking I had applied. Now granted, 1:1 may have been too thin but that is what I usually do. My guess is, the nature of this color just is not amenable to being laid on future, it probably needs the flat primers that I usually do. Anyway, I have a grenn glob mess and now am trying to figure a way to clean it up. I will say this, I have never seen panel lines so accentuated. The paint ran right off them. Panels are somewhat green after 2 coats and the lines are silver.
Anyway, it was an experiment and now I have to try and clean this up to make it respectable. No harm, just didn't work in this instance.
