I've now had a few days free to apply some weathering. I decided to weather the hull first so that the wheels could be weathered before the skirts went on. In hindsight, I probably should have kept it to just the wheels and running gear, but I got carried away and did the whole hull.
I used Flory Models washes for the first time and I like them a lot. I like treatments where you apply a covering and then removed it until you have the desired result. It makes it a lot easier to avoid over doing it.
As you can see from the above picture, the initial application looks like too much.
The next step is to remove the wash with a damp cloth or cotton bud. With the result that the weathering is toned down a lot.
I really like the grubby effect that resulted.
I think I made a mistake applying white wash on it's own.
Although rubbing it back made it a more suble effect to me it looked a little unnatural. So I removed almost all of it. After the one application I used it in combination with the sand wash to get lighter brown washes, and that worked well.
Once I was happy with the wash effect, I applied Vallejo Desert Sand Earth Texture to the wheels and running gear. To blend in the colour a little, I then reapplied some wash over the sand.
The image below shows how the weathered hull compared to the still unweathered turret
The next step was to glue the side skirts to the hull.
There was a little touching up to do (around the edges of the skirt mainly) and the end of the gun need to be black.
With that done, it leaves the weathering of turret and side skirts to do.
