Multi-tone car paint

I'm currently doing a little boat racing game for xbox 360 with a couple of friends, and so i temporarily left the wonders of Ogre3d, and started tackling with the XNA library. I'm currently very disapointed, i was thinking i would go from a render engine to another, but XNA is more of a graphics framework than a proper 3d render engine. It made me value Ogre even more. It's not just the material system (but that one is the one that hurts me more, damn), but nothing is structured there. There isn´t even a fucking Camera class or a Scene Graph structure. Bah. It has a really cool and strong community though. Anyway, i recently developed a car paint shader for the game. It has multi-tone (3 tones) fresnel interpolation, Flecks layer and environment mapping. I would really like to include also a wavy reflection normal mapping, i had it working, but somehow along the way i managed to screw it up, and this was already long overdue. Because of the fresnel nature this shader will work better on a curvy model, more thann a very perpendicular one, like the boat model we used (shiiiit).
So there you are, enjoy the pics, and the fx file.

And Here is the link to the Fx file
