Hi guys, thanks for all the positive and constructive comments, in regards to the coupler on the 1st car, it's something I tried and yeah it's a sour thumb. I will fix it, same with the ghosting on the hopper trucks.
My technique is simple, I use only paints and a combination of brushing, dabbing and spray painting techniques. No inks or dyes or chalk. Nothing against any of that I just haven't seen the need for it yet. I like the rustoleum camouflage earth tone flat colors in the spray can. I lightly spray the models then do the heavier work with brushes, paint sponges, even q-tips.
I will post more videos in a couple days, working 16 hrs a day until Thursday. Thanks again everybody!
