Not sure if this is the right forum (it's the only customizing forum). I'm dying a Classics Bumblebee into black to make Runabout. My question is whether red or yellow plastic makes a better choice for absorbing the black dye. I've taken car of all the other parts, except the car parts. I'm assuming yellow would be better, but I thought I'd ask anyway. I have enough Bumblebee and Cliffjumper parts to make this happen.
