Sorry guys I was in New Zealand last week so I couldn't reply sooner.
Anyway, window glass is of course different material than the car paint so that's why it's not on the same UV map. At the moment (due to me having a lot of stuff to make this work as it is) it's not possible. Same goes for the black bits such as the canards on the front bumper so for this comp they're going to stay glossy black. Text on the hood is just another reference to see where and how it's laid out on the car. Just ignore that and make your own decals on it. You can easily just screen blend the UV map and paint under it. When you save, turn the reference UV map lines and silly reference graphics off. I'm sorry if the bonnet text makes it a little messy.
I was thinking that after the comp I'd send you guys the renders so you can touch them up however you want to and post them somewhere else, like deviantArt. Maybe add some small details or do a background swap as well. How would that sound like?
