Micro-abrasive cleaning system

I recently received an inquiry about a micro-abrasive system being
considered for a New York City project.  Has anyone had experience with
or heard about EXA Systems (micro-abrasive cleaning system, used on
Notre Dame and Chartres Cathedrals, centered in Geneva with offices
in Norway, France and the US)?
