Thanks guys.
Fast Heinz - you are correct. I must have made my runs short by only having 57 links. That's what I get for assembling the tracks under the influence of a good bottle of Cabernet
Mobius - The light dusting technique is pretty good for any build as it helps to blend everything together very nicely in addition to replicating the layers of dust that build up so quickly.
Thanks for the Birthday wishes for the Mrs. The kids took us out for dinner and we had a really nice time. It was nice having them pick up the tab for a change.
Here are a few shots after some "mud washes". I wish I had some MIG pigments in the stash as I think they would be perfect for the effect I'm looking for. Unfortunately I was building the Char for the Blitzkrieg GB over at Armorama and didn't think of using them until it was too late to order them in time. Basically what I did for the mud streaks is put little blobs of Burnt Umber and Raw Sienna oils on the top of the slab sides just under the tracks. Then using just straight turpenoid and a wide brush I dabbed the turpenoid loaded brush along the edge of blogs so the pigments would run down the sides. I also put a blob of burnt umber in each of the mud shoots and ran turpenoid through the shoots from the top (since I had opened them up earlier in the build )
