The model is made from Elapor, which is a tough foam with a waxy surface that will not take paint. Multiplex sell a primer which is unpleasant to use but does key the surface effectively. I rollered on Dulux RAL 9003 (Olive Green), masking off the obvious areas of white, then after some more masking, rollered Dulux Black into the invasion stripes.
The windows are Tamiya Light Blue, extending the wndow area on the kit by about 50% to make a J4 glasshouse.
The feet are just 12” long.
