So after a bath in simple green and some scrubbing to remove the old paint job, I primed up the Scorpion Grav Tank for my Mymeara Eldar and got a base coat down with the airbrush.  There’s a whole lot more work to go and I’m really not looking forward to painting the giant gems on this thing.  I still have a lot of trouble making them not look terrible.  I might try masking the hull and use the airbrush as that could give me some nice gradients.
