the body design would work much better on the rb4, I was able to transfer a maserati (close in body design) skin over pretty easily on an rb4 a couple weeks ago, but then decided I didnt really like the skin that much
but to put it on an xrt would indeed be difficult.
Huh? I don't know what are you talking about anymore, I suppose you trying to figure out how to make the blue darker. I haven't used Photoshop myself but PSP has this tool you can replace colors with. Or you could just modify the colors of the layer(s) with some filter type of thing which alters the color curves and such.
