A few months ago, I finally got around to painting up my YT-2400 model.  Once the idea of the Rainbow Dash Warrior occurred, there was just no escaping it.  This being Star Wars, the rainbow paintjob is of course a bit on the faded and gritty side.
To get the light blue tones of the body, I gave the whole thing a brushing with Model Master’s French Light Blue, inked the lines with a blue .005 Micron Art pen.  Whenever some of the ink spilled up out of the panel lines, I shmeared it across the top surface with my finger to add to the general weathering and variegate the blueness of the body.
