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

Very Good Product. Helping fix my brother's car with white smoke coming out of the exhaust. We check beforehand whether we have enough motor oil. WE REMOVE THE THERMOSTAT. We flush all the coolant in the radiator and engine. This product ONLY WORKS WITH WATER. Add water from a garden hose. Then we leave some space to fill this entire bottle. We started the car at idle until the temp gauge and fan worked for a good 20-30 minutes. Then turn it off and let it sit and cool for 15 minutes. Then we start the engine again for 30 minutes to let it idle so that the system circulates with this chemical and we drive for 10 minutes. We FIX the symptom from there. There was no more white smoke. Notice two things we're doing here: We're removing the THERMOSTAT and we're filling the system with ONLY WATER. VERY GOOD PRODUCTS. This material can only be used with water for caulking. If you used coolant, it doesn't seal as we know it to. That is why you should flush all the coolant and only fill with water. If your car has water in the engine oil dipstick then I think you have a bigger problem than this fixable thing. This will only work on an engine that has white smoke coming out of the exhaust and there are no white water bubbles in the engine dipstick. These are the two main factors to consider before complaining about it not working.
