Bruce, I know Dan "ViperX" has done it, I'm going to get it done too. I've had a couple of chips on the back section of the wing in addition to the Gurney flap. You can tape the edge for the track which is fairly easy, but you'll get tire and rocks on the top section, so unless you want to tape the entire top side, use the clear bra.
In addition to the work you've done, I'd recommend doing the first 6-12" of the roof, and the sections behind the hood vents (in addition to the hood just past the scoop). I've also done the doors from the crease by the mirrors to the bottom. Mike
