Very nice paint finish Geo, and as noted, it's evident you've got to grips with the squirty stick.
Normally, when I plan a spraying sequence, I try to do the lighter colours first, especially if this is the 'main' colour, and then figure out which areas of this colour will need masking, not only for demarcation, but to prevent overspray getting onto areas where it shouldn't. These will more likely be the bottoms of the tail-planes and the fuselage around that area, perhaps the fuselage near wing roots, etc, etc.
It might involve a lot of extra masking, over and above what's needed for the colour scheme masking, but well worth the time and effort.
