I've been mainly using (Graffiti decals) paints and solutions to weather cars. I recently have come across a dry weathering powder at a train Show, the getting used to the multi variations of powder in this kit and the applications depending on the material is a bit tricky but fun to work with. I recently picked 4 small tankers to test- to remove the "newness" and on a couple of them to add some rust affects. The powder is much more forgiving than the wet applications. Some before and after's.
