Chris Ubing Well, I tried panel accent coloring on the SU 27 project, and I am afraid that I failed miserably. From what I have found out, you are suppose to dab a tiny bit into the seems so that it spreads throughout the panel. I didn't do that so that is that. I will finish this flanker. The base color is sky gray (tamiya) and make an attempt at camouflages, but I am afraid that the model is already ruined. Live and learn.
