Been busy at work for a while, but wanted to thank you guys for viewing and commenting ...
Gino - Thanks for the tip on tail lights. Good thing I read your comment twice because the first time I missed the fact that the entire right side are black out vs. red.
Paul - No base for this bad boy. I'm still trying to get the basics of construction and weathering, so for now everything is just going onto a shelf in my closet (after a victory tour of the fireplace mantle, of course).
Stefan - I used MIG pigments with fixer to create the mud. And you're right, I missed parts of the running gear like the drive sprockets. It isn't noticeable just looking at the model, but it's clear as day on a high resolution photo. Time to start taking pictures before I call a model finished, I suppose.
Mike - We'll have to see whether this was a fluke or I keep improving.
