I am going to be working on a new car and need to know how to make a realistic Matte Black paint job? Any Ideas or tips? Also how about color matte paint jobs? THANKS

That belongs into the Help area.
Depending on your base image and its color there are different ways to matte paint.
With some paints it´s easy, but if you have many reflections on the paint, you will have to rebrush everything, I think.

Matte paints are the worst, cause if you don't get it 97-100% it just looks toony. I have seen maybe 1 or 2 successful matte painted chops out of I don't know how many! Can't really give you any tips, other then to maybe start working with glossy paint first, and then when you master that go over and try matte.

Cheers!
