No 3D model is much without suitable textures. CG Choice Award Winner Stefan Morrell shows methods and tips on painting high-quality hard surface textures in this tutorial.
The tutorial is a very interesting and educational read that artists on most levels can learn something from. The tutorial is Photoshop-based, but can be followed using any other 2D graphics application, such as the Gimp, etc. It covers not only painting diffuse/color maps, but also bump maps and specular/reflection maps + gives a few assorted hints and tips. Make sure you read all the parts. Paint away!
