quick pan pastel weathering for black cars & locos

(1) As a teenager growing up in Providence, RI in the late '60's, I saw many Penn Central locos that were all kinds of grimy black and dirty looking. (2) Now, I am modeling the BN in the Seattle area in the early 70's, far away from the Penn Central's territory, and need to stay focused on that. (3) The way retailing has evolved, if you don't grab something as soon as you hear about it, it's gone - regardless of if you won't need it for many years, if ever.

In other words, Rapido just came out with a super cool Penn Central black RS-11, and Bowser came out with my favorite short ore cars in PC black, and so I had to have some. But shiny black didn't look right, so one day Tim Taylor was over here and in about 2 hours he used just 3 shades of Pan Pastels to weather 8 ore jennies, and the next day I spent about 30 minutes on the RS-11, and now they both look great! Photos below, and here's a video of them all in action. It's amazing how easy and quick it is, and how good it looks!
