I am about ready to build and paint some N-Scale DPM models. Assembeling them seems pretty straight forward, but painting is a different story. After searching The Gauge, I have found some advice, but I still have a few questions. First off, I would really like to stay away from needing to invest in an airbrush. So, my questions are: 1) Base-coat: Spray or Brush? 2) All coats: Enamel, acrylic, or other? Also, what are the benefits/drawback to each?
