Airbrushing - check! (Patreon)

My friends, last night I sprayed the rusty base coat and today was happy color day! 

The rusty base is a black primer, flat brown + flat yellow for the rust tones, German grey for the greyish stains and some AK Rotbraun for the rust primer. 

White base color is flat white + dark yellow for that off-white, creamy tint. 

Faded blue is flat blue + white, and the rotting vibe was done with Ammo Shaders: Light Rust, Olive Drab, and Grime.  

So... what comes next? A pin wash, then painting all the details and emphasizing some of the rusty chips with a dark rust acrylic paint, then some rust streaks with enamels... and then debris, dry leaves, and moss!
