Well, I managed to wrestle the compressor back downstairs, and had quite an eventful afternoon (attempting) to paint the Wespe.
I gave everything a final cleaning and used the airbrush to dust the parts off one last time.
Then I painted the entire vehicle with a custom-mixed Dark Yellow, 90% XF-60 Dark Yellow and 10% XF-7 Red. The red corrects the overly green tone of the Tamiya color.
I began painting a wide, random camouflage pattern with Tamiya NATO green, and managed to commit the biggest airbrush mistake possible - spill the paint in the color cup onto the nearly finished model! Fortunately it was only a small area and was pretty easy to fix.
The finished camo, ready for detail painting tomorrow. I deliberately add a visible 'squiggle' to the green to give it an uneven, field-applied look without being lumpy.
At this rate of mistakes, I ought to be done by Christmas
