Weathering Techniques in N scale Part 1

Thought I could make this a one-video deal, but here's part 1 of a 3-part series on weathering. We're going to weather three Athearn Railbox boxcars using three different techniques - weathering powders, washes, and airbrush. Hopefully you find something useful in my musings.
