Are you talking about real carbon or vinyl effect carbon ?
The vinyl suffs not too bad, you might just need a bit of super glue around the edges to prevent it peeling back around the ash tray.
Real carbon is a pain in the ass, I did mine last year and never got round to finishing it,
The main probelm with real carbon is it always wants to lay flat so trying to get it to follow very tight complex curves can be very difficult, it's also very expensive when it goes wrong.
If you intend to use real carbon and you've not used it before I suggest you start with something flat and simple first, it's nowhere near as easy as it looks on the videos.
