Ashford formula has been used on many sport arenas in the past years. The stadiums include:
United Center: Home of the Chicago Bulls
Safeco Field (1998): Seattle Mariners
Staples Center (1998): LA Lakers
Georgia Dome (1991): Atlanta Falcons
Gillette Stadium (2001): New England Patriots.
Now, many years after sealing, the halls of these stadiums have a sheen that gets even better with use.
