I do like Humbrol's Light Olive, especially when you add a thin gloss varnish layer...
This is my first chance to see the BA-10 and BA-20 together in their final base colour and they do look a really sweet couple! At the moment I am trying to ready the god awful UM acrylic tyres, the UM kit maybe better than the ACE BA-20 kit, but I wish I had the ACE's hard plastic wheels for my BA-20.
However...I have a cunning plan.
So while I tinker with this I will move on to the decals and also get the wheels on the BA20.
