Good morning!
It’s taken me a lot longer to get these done than I had anticipated, (life and all that, you know) but I finally completed my latest batch of hoppers.
I made some adaptations to my “two-tone” rust approach, and made more use of some of
@TLOC ’s techniques (wet-on-wet, alcohol-thinned Tamiya white with X-21), and have, I think, some greatly improved results.
The two-tone approach I used in prior batches (photos in prior posts in this thread) consisted of Mission Models Standard Rust (for new, brighter rust), and Vallejo Air Burnt Umber (for darker, established rust). For the new approach, I created three mixes from those two colors, for a total of five tones. From brighter to darker, they are:
1. Miisson Models standard rust (MMSR)
2. Two parts MMSR to one VBU
3. 1:1 MMSR/VBU
4. One part MMSR to two parts VBU
5. Valero Burnt Umber (VBU)
I’m going to refer to these tones by the numbers above for the discussion of this batch of hoppers.
I had a second Atlas 90-ton hopper to use as a test piece. I decided to use it rather than clean off the first, as I wanted to see them side-by-side when done.
So: I started with a brushed-on wash of #2 for panels an other areas that were to have large-scale general rusting. Then, while that was still wet, brush on some undiluted tone #2 whereheavier rust was advancing, then, draw it either up or down to the panel edge, away from direction of advancement of the rust. Then while that was still wet, do the same with #4, starting a bit further away from the front line of advancing rust.
The goal of using wet-on-wet was twofold:
1. Smoother color transitions
2. Avoid abrupt layer buildup.
Here is the result, prior to chalking and sealing:

And here it is with the first test car. (showing the other side) The first test car was intentionally understated with the rust, but this time I went heavy with it, as efficient use of a test piece should include testing out everything that you’re considering, so long as you’re not putting on too much.

And here is the finished car. The weathering chalks were Masters Touch earth tones light dark grey mixed for a medium/lightish hue, and a dark gray from the Sargent Art gray tone assortment.
The chalks made the rust areas darker (not really a positive, as my room is a bit dimly lit), and it pulled the colors closer together & smoothed out the color transitions.

The camera was up close and with the flash on, to be able to get the colors to show.
Despite that, I think it’s the best rusting job I’ve done, bettering even the other cars of this batch.
Trucks weathered with a 1:1 mix of Mission Models Brown (just plain brown) and VBU. A little dusting with medium brown and dark brown Master’s Touch pastels, about 1:1. Wheels weathered with the same chalk mix. Did all wheels and truck for all cars of this batch the same way.
The other cars:

That one above was #3 and #5. Probably “more realistic colors,” but too dark in my light. Don’t really like it, but it gives some variety to what I’m cranking out, so it stays.

These remaining three, I went for really only minimal rust:

I really hadn’t worked much on relatively clean cars or heavy rustbuckets, so I decided to focus on adding a few of each with this batch.
