The stipple looks very convincing! I very much look forward to the fuselage 
Thanks Ben - hope my described process was helpful.
After closing up the fuselage I tried my best to mask in and around the engine. The cockpit was easy with some chunks of soft sponge for that. I knew there would be some touch-ups to do near the engine & MG with overspray almost inevitable there. The pattern of stipple was applied with the thicker paint mixture of cloudy yellow airbrushed at about 9psi in short, sharp bursts with the nozzle at a wide enough setting to get the desired effect.
Cheers,
Gary

Randomly applied coloured patches mixed as per the instructions sheet using the XF-71 as the base.

The finished stipple pattern applied (which is less prominent after a gloss coat added later).

Over-spray on the engine, MG and struts would be touched up later.
