I did a project with anti-graffiti laminate on exterior printed graphics for a local high school. I did a lot of research on different anti-graffiti lams, and I was really disappointed to find out that they have a shorter exterior lifespan (3 - 5 years tops) than a good cast laminate. It was a trade-off for the school, we decided the risk of vandalism was greater than the need for longevity.
