One of my (2007) Christmas presents was a Grey Knight Terminator with a Psycannon.
The model went together very easily.
I based the base with parts from the Warhammer 40000 basing kit and Games Workshop modelling sand.
I then gave the model a black undercoat.
…and then I lost interest. However I have got it out storage recently. As you can see the model has suffered by being in storage and there are parts of the model where the undercoat has been worn away. I don’t think though I will redo the undercoat at this stage.
I decided I would then give the model a basecoat of Leadbelcher.
I has forgotten how dark Leadbelcher can be, probably exacerbated by the black undercoat as well. Wondering if I should get a lighter metallic spray for the Grey Knights armour.
