@trackmagic:
Did you get the decals from the same place that Viracocha got his? What are the part numbers you ordered?
I started to paint my pieces. They looked really good when I sprayed them, but the details are hard. I bought a really fine high-quality brush from the hobby store and I still have trouble making thin-consistent lines. I am thinking of starting over and trying to use a toothpick as a paintbrush.
After re-reading this, I have some advise that may help. With the roundels, for example, British, Paint a yellow circle. Then put a blue ring inside, then a white ring, then a red dot. That way, your rings don’t have to be perfect.
