Hi and thanks for downloading.
the shader is based off of the popular car shader which is used most everywhere, and I improved it a bit. I mainly just changed the colors using one main color and a few mixes so that the change to color of the car, you only have to change the one main color wheel and you are good to go. So it is basicly the same as others, but a lot easier to use, and for some reason, I find that it give better results.
You don't have to attribute me, but if you are willing to, please go ahead and give me some credit ;)
have fun, and I would love to see your renders,
