Probably my favourite Indiana Jones film is Indiana Jones and the Last Crusade. The combination of archaeology, mythology, nazi soldiers and lots of wonderful pulp action. Though we know the tank wasn’t real, and there was no actual historical version of it; I am sure most of us who have thought about recreating the Indiana Jones films on the table have wanted to use that tank.
Having constructed the model I gave the tank a white undercoat.
I did the underneath first followed by the top.
The turret was undercoated separately.
