First coat to go over the preshading was Tamiya XF-20 Medium Grey. I went too heavy and covered all the preshading and then remembered I was meant to spray the darker colour first for the camo markings. So I decided to lock this colour in as the lighter edges.
The first dark coat I tried was Tamiya XF-84 Dark Iron. I didn't realise it was a metallic and it came out as a dark sparkly jet. I didn't like it, so I went over it again with a mix of XF-85 Rubber Black and XF-2 Flat White (10:1).
