After 2 years of a lot of driving, I don't have any evidence of rock chips on the nose of my car or the rear fenders. For sure, you don't have to look for a rock chip, but I've had people look hard before they could even fina the edge of the Invinca Shield.
Below is a shot of the technician applying Invinca Shield to the front of my car. In the process, he was developing the pattern for ERA noses.
