Review on Protect and Shine: Blue Magic 1008-24PK Liquid Glass Metallic Seal-Up® - 11.4 oz. by Sanny Hoffman

sealed Toyota Camry Hybrid engine that drove many miles with a blocked water pump. After repairing the pump, one liter of coolant is left every 100 km. Cylinder head gasket or cracked head. Driving with a leak has also discolored the coolant. The exhaust is probably in the coolant. After flushing the system and adding water and sealing it, the leak was gone and the coolant stayed crystal clear for the last 10,000 miles. It didn't clog the radiator, the core of the heater, and didn't cause the backup water pump to fail. Fortunately, this happened in warm weather. At some point I have to flush again and then refill antifreeze. I believe this will hold up as I haven't lost a drop of coolant and haven't had any misfire codes or any other codes since I added it. This was added to the car's mileage of over 52,000 miles per year.
