Note: This tutorial has a had a small modification to take into account changes in Blender (ngon faces introduced in version 2.63 onwards).
This tutorial shows how to make a model of a Coke can and wrap texture image files around it using UV mapping.
In the second part of the tutorial it shows how to use more than one material and how to assign them to selected faces of the mesh.
The tutorial shows how to modify a cylinder so the shape is similar to a soda (fizzy drink) can. The tutorial shows how to get a cylinder projection from the model and map it to a coke can label image.
