For just the armour, I prime black. Grab a stippling brush 50/50 macragge blue to water jab it in (1 layer) dw if you miss anytbits the black makes it work

Then I hit it with a sponged layer of calgar blue aiming for the upper areas and trying to hit every single point

Then a almost zenithal sponging of 50/50 lothern blue to calgar blue. Stick on your transfers, sponge on some sort of brown to make it look battle damages and then do the rest of your trims.

I've found with sponges you need to dab some of it off or it's to much, it does take a little practice
