Thanks - I used a satin black (I think it was Krylon) spray paint...Gives it a little shine. Then I dry brushed with Testor's silver.
Phil - for the stock, I used one of those polyurethane and stain combos - I think it was a dark/special walnut. I put like 4 coats on it. In between each coat, lightly sprayed it with flat black spray paint to give it an older, well-used look.
The stock box was built similar to my hardware split plugs, layered sintra. The bottom is made from 2 pieces of sintra just glued together. The third piece of sintra was cut so that it would make a lip around the edge. It was basically the same shape as the first 2 pieces, but had the inside removed to with in 1/8" of the outside edge.
I then used glazing putty to fill the cracks, painted it black, and dry-brushed it with orange. I really wish I could've gotten some orange plastic and then sanded the black off of it. Makes the weathering more realistic up close.
Hope that helps, PM me if you need more info.
