I have not... but I have seen videos online where they did. Unit attaches to an exhaust vent to pull in fresh air to pressurize the cabin. Then technician sprays soapy water around any/all outside seals such as around windows, vents, furnace intake/exhaust. I recommended my dealership buy the unit to find the source of leaks in my Wildcat and to make extra revenue when interstate highway passersby came in complaining about leaks. They would not.
