Not that long maybe 6 nights scattered over two weeks. Much faster than my low viz custom. This was just going to be a guinea pig for the plastikote and fusion paints, but I got really into it.
Basically received the hikaru that had a botched panel line job done to it so black ink had run/smeared all over it. Dunked everything except the legs in Pine sol and sanded what was left of the paint. I didn't primer it just airbrushed light grey Tamiya over the white bare plastic for all the panel lines and then drybrushed the streaks on with oil paints.
Blue Plastikote saved alot of time as only needed about 4 light coats. Followed up with Darker blue Tamiya airbrushing for panel lines and careulian blue oil paint for the streaks.
The pilot fitting was the only real difficult part as you need to shave down the seat on the early 1/60s that didn't come with a pilot.
