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

It works as expected though. I followed the directions on the bottle. The only thing I did extra was remove the radiator after machining and rinse well. I also drained the water through the top hose where the thermostat goes and washed off excess water. It was easy to remove, also because I didn't machine the radiator. I've used it to fill a small crack or hole somewhere in the head or block that we can't find. The thermostat has already been removed during a system flush treatment and I highly recommend removing it for this flush.
