I'm no expert but am pretty sure its all black under that front bumper that wraps around on the guards. Get on Youtube and search GMHNUT and then watch the HX Commercial range including Sandman. About 30 seconds from the end you'll see the Sandman drive up and whilst the image quality isn't great, it looks all black under there as well as the bottom of the guards.
Thanks buddy I thought the same thing, im booked in for paint mid June and the spray painter looked at me silly when I told him this is how its done. Better to 2x check. I will check out the You Tube link.
