Simply to play devil's advocate. Would they be easy to paint black? I did that with a C30-7 a number of years ago and it was really easy.
I understand that it is frustrating to receive something this is not as advertised. However, I've come to the conclusion of why ruin it for someone who doesn't know any better or for that matters cares?
Just my opinion anymore in a post-modeler age of model railroading.
