Well... my first weathering attempt has just rolled off the painting table and onto my layout. Part of the motivation for this is I have 3 Atlas N-Scale Boxcars that were "too old" for my layout, in that they had roof walkways. I decided to try and modify them by pulling off the roof racks, putting putty into the holes, and then painting the roof. I figured while I was at it, I'd try my hand at weathering, and even a bit of graffiti. Here's my first attempt... It's not a rivet-counter's ideal, as the ladders on the sides are still too high, but it was more an attempt to get the feel for weather, while actually being able to make use of some rolling stock I actually had on hand. I have two more boxcars that are on my painting table, but this one was the first to be completed. I may still dust this with another layer of dullcote, since it has a bit of shine from one of the gunge washes I did... If I do that though, I'll provide another picture after the other two boxcars are done, and I've dullcoted all of them. Basic shot: Closer look at the same side: The other side: Any feedback for a first attempt before I move onto my other two?
