Here's the tech in a nutshell.....(I'm assuming it's a resin kit or a poly stat. ) spray the entire piece using Krylon Ultra Flat Black, or use a flat black paint w/ a brush. You will now use a technique called "drybrushing". Dip a flat brush into your paint, then wipe the majority off on a paper towel. Using a flicking and scrubbing motion, apply the paint to the piece, going against the detail. This will eventually destroy the brush, so use a relatively cheap one! Even though you wiped most of the paint off, you will see it deposited on your piece. Now, use this technique to heavily drybrush Raw Umber over the entire piece. Then, using a bronze metallic color, drybrush this over the top of the Raw Umber, concentrating it on where you want the highlights to be. When you're done w/ this, the final step is to VERY lightly drybrush some Golden Interference Gold over the tip tops of the highlights you did previously. This should be looking exactly like worn bronze at this point. If you want to add a patina weathering effect, merely use a wash (nothing more than acrylic paint thinned w/ water) of a turquoise green paint. Repeat if necessary.
