Review on 💙 Blue Magic 1116 Liquid Glass Metallic Seal-Up: Professional-Grade 22.8 oz. Solution by Dushawn Walker

My 170,000 mile Chevy Astro has a leak at the intake manifold gasket where the engine coolant is escaping. I tried another similar product, the instructions say it can be added to the antifreeze solution. Yes, it did over 10,000 miles, but ended up with a clogged radiator. After I replaced my clogged radiator with a new one, the intake manifold gasket started leaking again. So this time I bought Seal Up and followed the instructions. The leak disappeared after 20 minutes of engine idling. I also removed the thermostat for unrestricted coolant flow during machining. After 1000 km still works great and works.
