Review on 🚗 McKee's 37 Hydro Blue Ceramic Car Wax Spray: Advanced SiO2 Hydrophobic Top Coat Paint Sealant Protection, 22 fl. oz. by Michael Vargas

These new nano-coatings are very popular in the automotive refinishing industry. Picking one to try was a hurdle. I trust 37 McKee products because they're good enough for Wayne Carini, they're good enough for me. This Hyrdo Blue works as advertised. Wash the car, spray while still wet, rinse off thoroughly and dry the car. Left my Genesis with a deep glossy shine and an extremely smooth finish that only sheds water. Did my car last weekend and it has been raining moderately all week and my car is almost clean as the rainwater just rolls off. Watch the video on their page for instructions on how to use it. I have painted my car and my wife's car with 1 bottle and will report that you definitely don't need to use as much as you think as they note in their video. First I used about 2/3 bottles on my car and sprayed each part of the car lightly (6-8 sprays per panel). Then when I switched to my wife's car (Subaru Legacy) and only had 1/3 bottle left I had to be more careful to get full coverage. Well, the end results were identical, so lesson learned. My biggest question now is how long will this last? I'll wait to buy more but even if it only lasts 2-3 months it's still a wonder product for usability. If it lasts, a 1 gallon refill will most likely be purchased to save on application costs. Update: A month later the tarmac is still holding up well and we've had a lot of rain here in the North East. The finish isn't as "smooth" as it was in the first week, but both cars still squirt like they've just been waxed. As it was warm for December I gave another thorough wash and applied Hydro Blue and hopefully both cars will get through the winter before I can wash and apply more in the spring. I have a 1 gallon refill to be more economical and I can tell you that you should be able to do 3 mid sized sedans with a 1 16oz bottle. If you use more you are really just wasting the product as there is no real improvement in using more product.
