A couple weeks ago,
Firestorm asked me how I did my urban stealth paint scheme that I posted
here. I was working on a new set of sniper & marker drones so I made sure to document my progress. I apologize for the poor photos, my light box is in storage right now, so I had to rig up a special system to get somewhat decent photos.
Here goes:
Step OneStart of with primer, your favorite kind will suffice. Typically you'll choose it according to how you want the scheme to end up looking. Since I hate black lining & I'll have a lot of black spaces on my stealth models I did black. Here you can see the top of the disk prepped for starting the camo scheme.
Step TwoWith the area prepped you line the basic idea of the camo lines. I used codex gray with a 3/0 round brush. With that width brush it takes about two passes to get the correct width and points of the lines. Don't worry about getting the edges too sharp yet since that is done later.
Step ThreeWith the lines in place I added the surrounding color. Here I used shadow gray. For starters I painted the basic shape of the shadow gray with the same 3/0 round brush. Then to get the sharp edges between the shadow gray & codex gray I switched to a 10/0 brush, slightly overlaying the shadow gray on to the codex gray until I get a sharp, crisp edge between the two.
Step FourWith the shadow gray in place I then switch to chaos black to finish sharpening up the paint job. Using the 10/0 brush I go around the outer edge of the shadow gray, then fill in the black between the codex gray lines. At this time, I make sure to keep the lines as even as possible.
Step FiveWith the camo done I then add gemmed "stealth nodes" and paint in the rest of the details to finish up the model.

With this scheme, be prepared to take a lot of time, and lots of practice steadying your hand. I'll usually brace my painting hand against a table to stay steady enough to get straight lines. Overall it took me 13 hours on my first model, but now I can finish up a model in about 1-2 hours. Don't be afraid if you mess up, if you are using thin enough paints, you can easily paint over your mistakes to get a nice finish.
Any questions, please feel free to PM me.
