Hi guys! After my failure to build Merkava , I've decided to try and learn to make some whethering on armor models. I have a scanned version of Maly's T-34 that I'd repainted using Photoshop. Now here's the question . How can I weather an armor model (or any model , I believe that oil stains are similar on plane too ) ? I know how make darker and lighter sides and panels but how can I make something like rust staines, dust even maybe bare metal ? Any ideas ?
