By BigAl3DThese materials are made with Corona before they added the node system, but they are perfectly compatible. Corona uses a system that the nodes let you look at all the materials, not each material contains its own node window.
Anyway, I started with this great material from Eduard Riegel at Corona-Materials.de. The scene file also contains a cloth mesh object if you need to show that type of material.
I then tried to match as closely as possible real-world Honda car paint colors. Please make something nice and post back. Enjoy.
