Any suggestions on painting the Walthers Union Station? The one pictured is on a club layout and to me looks like "flat grey primer on plastic", at least up close. I was hoping to find something that might look a bit better. I don't know if there is a technique or paint that would give a slight amount of texture to the walls. I was thinking of doing mine in something closer to a sandstone color.
Added to the existing thread as there was some discussion of this Walthers model.
