Okay, it's masked up for the EDSG, but since it's now 2.49am here, the only thing I'm going upstairs for shortly is sleep, not paint spraying...
The tip tanks were a dilemma, i.e. how to deal with the EDSG/Sky demarcation line?. The only FAA aircraft to have tip tanks were Sea Venoms, and since they were desperately short of fuselage space for squadron badges, they usually painted the tanks in squadron colours, typically chequerboards or stripes. On the few pics I could find where they wern't stripy/squarey, they're all-Sky, which looks rubbish even if it's genuine. In the end I went for the pragmatic solution of top half EDSG, bottom half sky, on the grounds that a) it'll probably look right and b) it puts the colour demarcation right on the dodgy seam lines on the model, thereby helping to hide the latter...
Demarcation-wise, I've kept the fuselage line totally separate from the wing roots, i.e. more like an Attacker than a Sea Hawk. The bit of Sky between the fuselage line and the wing root is still narrow-enough that I had to use 3mm non-Tamiya tape on it, as well as on the curvy bits of the line since it bends better.
Just rememberd that I havn't masked up the tailplanes...
Oh well, at least that's not hard....
