I saw a
post in the Weekend Update about this stuff and decided to give it a try.
When I first got it I just shook it up and painted it on, thinking it was just rust colored paint. And it was quite thick so I thinned with water. And it didn't look quite right, very yellowish. "Junk!" I exclaimed.
Well, no--it was my fault. I didn't read the instructions. It's really not paint--and there's definitely a technique to it. You need to put it on thick, do multiple layers if you want, and, importantly, *wait for it to dry thoroughly*... After looking at a YouTube video about it I tried again and got some better results.
The rust colors are just amazing--it really looks like rust; I'm guessing this is because it contains iron that actually oxidizes as it dries. Or Oompa-Loompa blood. Who knows. It also gets a really nice texture like scaling rust. In Z scale it's a little overpowering--you must apply with care unless you want a real rust bucket. But with a little finesse I think it looks good, even in Z.
Here are some trucks that were painted black, and I dabbed on a bit. (Note: the wheels have brown paint on them, not the Dirty Down)
Here's the roof of a boxcar that I gave a nice thick coat--this would look awesome on the floor of a well-worn gondola:
And a newer roof I lightly dabbed in a few tiny spots (with AK Interactive True Metal 457 Steel metallizer on the roof btw):
