I have a 997S Basalt Black Metallic (delivered in Feb. 2006), and I had the dealer install the 3M clear boat bra. It worked on the way home when I took delivery, protecting the car from stone scratches on the interstate.

However, with the black, it does show a line on across the front of the car, but with black, I don't see any "yellow."

I'll keep your improved car protection process in mind when I have to get the original replaced (as I assume I will have to do in the next few years).
