In 2011, Chicago officials were trying to impress the Olympic Committee to select Chicago as a venue. Part of this effort was directed to the boarding platform area where these officials would enter the city from their planes. AD708 was applied and there were concerns about black tracking of shoes and coat powder used to melt the exterior snow. In the spring of 2013, the Olympics had already chosen another venue but the AD708 was still performing and but getting dull. That could have been a bad thing except the facility manager estimates that 9 million people walked across the platform with roller bags. Enjoying the benefits of ease of cleaning, no staining and reduced slip and fall, he had AD708 reapplied.
