I am building RX-78-2 ver KA right now, I am consider myself as beginner, still exparimenting with preshading techniques.
I tried to use the Tamiya Flat Base X-21 (mix with little bit thinner) and air brush it over. I thought it was a layer of clear flat, but it turns out to be white and powdery after it dried. I can even rub it off with my finger over the model. What did I done wrong?
is the FlatBase not supposed to mix with thinner? can I mix colour with some
Flatbase to convert the paint to flat-based?
