How do I use reflective stuff?

How do I use reflective Materials/brushes? I'm working on my map for the contest and I was going to use reflective metals, but I don't know how.

You'll need to place env_cubemap entities in your map, and then build them using in-game console commands. The process for building cubemaps in TF2 can be found here.
