Chap Mei submarine.
I used 3 Tamiya spray colors:
TS-81 Royal light gray (x1) for the interiors;
TS-32 Haze grey (x2) and AS-4 Gray violet (Luftwaffe) (x2) for the exteriors!
I eliminated all the "kiddish" parts.

This is the first submarine for my Joes, finally!
I named it after Shooter (Sergeant Craig) died in D.D.P. "G.I.JOE: Declassified". She was the first G.I.JOE sniper and a cool girl!

Chap Mei did an excellent job! Initially I wanted to painted it all with flat black or rubber black then I decided to use various types of gray. I think it'd be perfect for Deep Six, Depth Charge, Shipwreck, Torpedo, Wet Down, Wet Suit, Tracker, Dr. Link Talbot, Ice Storm and Night Fox. Keel-Haul and Topside remain on the U.S.S. Flagg.
