As much as we’d wish it were otherwise, the world is seldom shiny and new as a toy on a shelf. If you want your train layout or diorama to look realistic, you have to find a way to represent the wear and tear of the real world, showing what depredations the elements can wreak on unprotected surfaces. One of the coolest and yet easiest to create effects is rust.
There are a few ready-mixed multi-step products that can do the trick, like Rustall, but it is really not hard to create the effect of rust using a few simple techniques and paint colors. We will use the techniques of “the wash” and “the dry-brush” as discussed in earlier articles to achieve the desired rust effect.
Paint and supplies:
Burnt Sienna and Burnt Umber(we use water based Liquitex in the bottle)
Silver acrylic paint (we use Apple Barrel or similar)
Testors’ Dullcote spray in the 3 oz. can
Powder (We use Bragdon’s Weather System rust colors)
Brown or gray chalk pastels
Dish soap – to add to the wash
Isopropyl alcohol – also for the wash
