Retributor Armor (Base) – Basecoat, I would recommend going thinner with this paint and multiple layers because Games Workshop metallics are typically very thick. Shake very, very well (and I advise an agitant.)
Reikland Fleshshade (Shade) – Wash the model extensively. I’d let a lot of it pool in the details and recesses as much as possible. The red from this shade really makes the gold pop and multiple lighter coats with a focus on the details can look amazing.
