When i was over in the states I did see that system, or at least one of those in the hobby shops. It was too expensive for the quantity you get and the salesman said it was rusty looking but not real rust!
I have in the past used MIG pigments which are dusts and work really well over a rust flat paint achieving that " orangee" leak stain, however I wanted more of a rusted look although I achieved more of an abandoned look!lol
I will share this cheap and very easy way to achieve the REAL rust effect although YOU will have to practice to see what you want it to look like and how you want the streaks to run, eg. off bolts etc.
I bought White iron paint used in decorating walls , vases etc. from my local paintshop and the patina to react and rust which is simply Hydrochloric acid , this you can get from home depot , garden shops etc, as it is used to clean.
I also used blue iron paint , difference is with this one you get the darker rust and with the white iron you get the greens and light oranges.
Apply the iron paint exactly how you want the rust to look, obviously from top thicker streaking to thin down. Then after it dries hit it with hydrochloric in the same way, never from side to side, the drips will be reproduced naturally.
This was done over a flat black surface and a humbrol hull red base.
I will post up the following pics that have the MIG pigments added of graphite, smoke and dark rust, which softens the rust and gives the rust look an even further WEAR look. Remember it looks like real rust cause it is!
Then seal with satin and there you go!
One important thing about this is that I would be testing all the above in whatever material you are using , as the brands and contents would differ, but here in Australia , the paint's brand was "Potters" and so was the acid but you can use normal hydro. The resin on the cart was not affected one bit as it is user friendly (the paint) reaction time is almost instant but naturally that was only one step, you have to tweek it to your liking.
I am more than sure 90 per cent of you guys could duplicate or even better this job as I have seen how you guys paint!!!!
I wish I could paint those heads.
If you need anymore info , ask away.

Very good point. They would be bright polished steel due to the friction from the tracks.
