I have already had a go at doing thickly muddied tank tracks, but the result wasn't altogether satisfactory...
You may have to take my word for it but the texture of the 'mud' I used - Tamiya's weathering sticks - wasn't quite right, especially for the 1/72 scale. I actually had one of my readers comment on this. But muddy tracks is such a basic technique in AFV modelling that I wanted to get this effect right, so I'm having a second go.
So, I did some research (referenced some YouTube videos) and plumped for a combination of tips on painting tracks supplied online and in a useful book I bought called 'Small-Scale Armour Modelling (Modelling Masterclass)' by Alex Clark..
A new product I am trying out - which I picked up in the ModelZone sale - is Vallejo's effects pigment. Normally I wouldn't buy this as it's expensive for what it is and a similar effect can be gotten cheaply by grinding up Conté crayons or pastels into dust. But this 'pre-potted' solution effectively saves me the messy grinding process!
Basically, my recipe for muddy tracks goes like this:
1. Start with a base coat of black on your tracks...
2. I then apply a very thinned wash of acrylic Khaki all over...
3. While the thinners is still slightly damp I dust the tracks down with a generous cloud of the pigment...
Alternating the effect
Now, I was going for a VERY muddy effect, but the 'mud' can be modulated to be less thick or a different colour mud to suit your chosen environment. I wanted a red clay type of mud so I used Vallejo's Natural Umber powder, but the powders come in a range of earth colours (likewise if you use the cheap Conté method you just choose the crayon colour you want).

If you want a thinner layer of 'mud' you simply use less powder and you can also dust off any excess with a brush as the thinners dries off.
Now remember, the powder is only held on by thinners, it is not fixed permanently. To do this you will have to give it a spray with something like matt varnish. At this point you can then add other track effects like metallic highlights or any additional washes that you might want...

A graphite pencil was used to give the metal tracks a metallic shine. Also, I used some dark brown wash between the track links. |
And there you go, heavily muddied tracks. A lot better effect this time than my first attempt with Tamiya weathering sticks. Importantly I think the effect matches the scale, and the 'clumps' of mud aren't too big.
