Here is some interesting reading I found that Mercedes has developed in higher quality paint systems, maybe we might see it on our cars soon, since we are part of that company.

Microscopically small ceramic particles provide a layer of protection in clear coat finish,
Remarkable advances in the area of nano-technology have allowed tiny ceramic particles – each less than a millionth of a millimetre in size – to be integrated into the molecular structure of the binding agent. These particles float around freely at first in the liquid clearcoat, before cross-linking as the drying process takes effect. The particles link in with one another in such a way as to create an extremely dense and smoothly structured network at the paint surface. This provides a protective layer and ensures that the new nano-particle clearcoat is considerably more scratch-resistant than conventional paintwork.
