Lee, Thanks for the comments. I'm not sure what Black wash is . I used a black .05 ink pen to not have to much black show as from the real car pictures I used they did not have very much black. I am working my way up to wiring engines back in the seventy's when I was building I would wire using the wax thread. I did find the BMF a lot easier than the old foil that the Jo-hana kits came with. I just didn't think about the tires. Again thanks for the comments.
