That's the stuff. I actually tried it today on 503, but I don't like how flexible it is and when you round the corner from the leading edge of the bumper to the sides, it either sticks out too much, or if you take a tighter bend you can make it so it sits more underneath on the sides. Either way, it didn't quite look right to me. Some might like it. The front look surprisingly good though when it's on the car. I just didn't like the transition into the sides of the bumper.
