Description/Information:
A nice demonstration how to do the "scratched painted-metal" look.
* The "stripes" you see that are used for the scratches are just an example, in most cases a custom-made uv-map is a better idea for the basic mask.
* Also the paint- and metal materials I used can be replaced with something better at any time, that's what the nodes are for anyway :)
On a related note: Now there need to be a way to get node-modified textures back into a bumpmap or something similar to make this even more powerful.

Oh, this stuff is not really that hard to do, in contrast check out this tutorial (this material uses some ideas from the tut):

Now _that_ is impressive ;) - although not really possible with procedurals or low-res textures.

A really cool way to use this type of material is by combining it with vertex- (especially useful with the vertex-AO script) or texture-painting.
A vertex-painted model ("Self-Shadow V-Cols" script):

The model rendered with a few tweaks to the produces vertex-colors ("Input->Geometry->Vertex Colors" Node):

I can upload this baby, but the downside is that one needs to modify the geometry (subsurfing) the model in most cases. A nice node-input for that gives a gradient depending on face-angles would really rock here.
The material itself does not provide any eyecandy (it's either completely metal or compellingly paint) - this all needs to be done by the user by setting vertex-colors
