I'm trying to create a "wet" surface for a runway - anyone have any ideas about to use the shader trees to get a realistic effect?

Can you be more specific? Do you want puddles, is it streaky, is the runway bumpy, are we going to be taking a picture of the image at the surface of the runway or a ways off? As a first shot given I'm not sure what we're doing just yet, I'd put two kinds of patterns in the color channel mixed with turbulence. One pattern would be asphalt, the other would be your water. Then I'd copy the same mixer into the reflection channel and mix different values until the "puddle" look was where you wanted it. This is just a first crack at it. Give us some more detail and we'll soak you! -Kixsupercool.gif

Well I have a texture map already for the runway - I'll try the turbulence shader and mix um up.

What you want to do is to use a specularity map, meaning a map in the highlight channel. I found a place in the web with a good tutorial.
