I have been working on my first car for about half a year and after watching countless amount of tutorials I noticed that there is no proper car paints to be found anywhere. [After posting the thread some guys gave me links to some paints that were good, thanks for those!] After taking some quick notes on how the layer weight node works from various tutorials I have come up with this material setup:
With flakes it looks like this:
[EDIT: Removed texture coordinates and updated the colors and mixing a bit]
Here is a quick tutorial about using the node.
When you don’t want flakes you simply disconnect the mix node to between the paint and the clearcoat layer.
If you want to have color you need to tinker with the nodes and mixing. Darker color always comes on top! Also try different layer weight values, it might look better in certain situations if you experiment with it.
The main thing is that when a surface of a car is looked from an angle it appears lighter because light gets “trapped” between the clearcoat and paint surface. Just like a fiber optic cable. But when you have a car with two or three coat metal-flake paint, the flakes shine and sparkle from the darker areas and fill some light in there. There is still a bit work to be done though because the reflections are not quite as bright as they should be.

Note how paint looks in the bonnet for example.

I couldn’t have done the speckles without help from this:
