To start it was given a wipe down (this was done a month after painting) to clear any muck from running. The maroon bits were heavily brushed with revel 46 and 87. Only do two panels at a time as as soon as the paint is on, you get a rag and smudge it around the panel, dulling it and putting muck in the gaps between the planks. The footprints on the rood were added with 46 and the muck on the steps too.
Make sure when rubbing the paint around to get it into the lower horizontal strapping and corners as the muck would collect in real life.
Add some railmatch dark rust to some open parts of the strapping in light but concentrated stokes, also on the hinges, latch and corners.
Over do these with a mix of 46 and 87 (or close, I used some 67 and 45 as well, all matt) dry brushed, licking the brush around the corners. This dulls the colour.
On the roof add some 75 around the edges, heavy on and then rubbed off to make the edges look like water has been collecting on them, like streak marks almost.
My no 1 rule is no BLACK. Black is not a natural colour, it is often grey and so everything was done over to chalk it up for word for a phrase. I have different techniques for different scenarios. This wagon is the sort that gets used but sits outside most of the time in an open situation but is also showing signs of age.
I will be continuing this thread for other vans, and another thread for more, like my crane wagon.
Thanks for the nice complements.
*Warning* Do not use a good brush, you are going to mistreat it a lot and so, dont buy the most expensive!!
