Here is the third vehicle that I finished recently. This is a Siler Heavy Tank from Khurasan.
I am planning two small opposing forces for use with Tomorrow's War. 30 figures and a vehicle or 2 on each side. And this is the main tank for the first side.
With the size of these vehicles, getting a smooth, consistent paint coverage is a challenge. I decided that using a colored primer would be good idea. I painted this with Army painter army green primer/base coat. This has worked very well, but at ~$14 a can, it is hard to change colors for a few vehicles. This has started me looking into airbrushes again. And the cost of a good air brush and compressor is still in the $200-300 range, which is steep but not out of reach. Some of the paint manufacturers are starting to make decent acrylic paint that is airbrush compatible. So, if I am going to keep doing vehicles and terrain I think I will be acquiring an airbrush in the near future.
