Weathering track solution?

Good solution to dip/coat tracks to achieve something like the effect in this picture? (not the rust) Thanks!

There's a few track guides on the internet but the effect there is just from running round a display ground and across fields where that tank is kept. It's dirt, dust and surface rust. Best way to get that sort of effect is to prime and paint your tracks then apply washes and pigments. The overspray lightly with whatever dust final colour you want, which you also apply to the tank. Sort of like a filter. Then sand back (or run the tank on concrete!) the expose surfaces. You can apply rust colours to that but they'll wear off.
