It's been a while, but I finished a few cars in the past several months.
The box car turned out OK. In the areas where I had messed up the base paint trying to remove the Lionel "forever ink", the decal edges are visible. In the other areas with the good paint, using the gloss & matte finishes, I'm happy with the result as a repaint.
The guys in the paint shop need to hold the CMR and Microscale stencils straight next time!
