My next build, Im going to work more on rust TEXTURE, like, with baking soda or something similar. On builds Ive seen, it makes it a lot more realistic. On my KV-2, the 'rust browl' Testors enamel just looks brown, until you start playing with it, adding metalic paints, letting it stain / run, etc .
Im happy with how it looks now.
