This just in... There was a big article in the HVAC Insider about how this Ford plant in Canada had several chiller leaks. The story goes that it would be too costly to shut down the chiller to repair the leak(s), so they just added a leak sealer. Now the leaks are all fixed and the plant avoided costly repairs. Follow-up... A branch manager from a United Refrigeration store tried to reach the Ford plant and speak to the "named" supervisor for more information. No such person, no such chiller problem according to the HVAC engineer. Never heard of the product, never would use it, period.
