***UPDATE*** I decided to paint in gloss black. more info available here
I decided to wrap the center air vent. I've used 3M Di-Noc many times before. This time I decided to try out the Brushed Aluminium version from 3M Di-NOC Series ME-904. I must say the texture is very good. It is not a fake printed wrap, its the real thing. It's very easy to work with and very forgiving. If you make a mistake, take it off and re-apply with heat.
Below is a picture of the new vent.
Also, here is a video showing how to apply the wrap:
