Hi, I'm new to this hobby and close to building my first model railroad (HO Scale) on a tabletop. My main concern is which way to paint the track. I'm using Atlas Code 83.Do I do it like this (painting with a brush) http://www.pacificcoastairlinerr.com/4x8/weathered_track/? or do I spray paint w/ rust brown and black? Also, is it better to paint/weather in place or separately (sectional track)? What about wiring and rail joiners if painted separately?Thanks for your suggestions!
