I was weathering some rolling stock recently and my son asked me why I never weathered any of his cars. He has collected some of his own over the last couple of years, he's 8. I explained to him that I never thought he cared or would even want his rolling stock to be as he says "dirty and crummy" I can't say I ever thought I would be weathering a spotlight car, I mean I try to only run somewhat prototypical cars. At any rate we decided he should have his first lesson in making rolling stock look a little more real. Here is the outcome.
