Hydro Blue PRO SiO2 Coating

27 reviews

Spray On, Rinse Off Ceramic Coating 

McKee's 37 Hydro Blue PRO is a ceramic-infused spray on, rinse off nano-coating that blankets your vehicle with a glossy, durable shell of SiO2 ceramic protection. Unlike traditional waxes and sealants that require hours of rubbing and buffing Hydro Blue PRO is applied AFTER you wash your vehicle while it's still wet. Simply spray on and rinse off. Hydro Blue PRO is safe and beneficial on all exterior surfaces including paint, glass, wheels, chrome, and plastic trim.

Do not apply to a hot surface! For best results, apply to a vehicle that was recently decontaminated using McKee's 37 Universal Detailing Clay. After you wash the vehicle, while it's still wet, simply spray Hydro Blue PRO onto ONE panel at a time and IMMEDIATELY rinse off using a strong jet of water. Do not apply to more than one panel at a time! A hood is considered two panels. Continue this application process panel-by-panel until the entire vehicle has been coated. Dry vehicle using a Turbo Car Dryer or M-Line Microfiber Towel.

22 oz.

    Hydro Blue Pro Si02 Coating

    Bought 2 22oz bottles of Hydro Pro Si02 Coating. Works great keeps the paint protected and rain water beading off the car's body and lasts long. I use it on every car wash and will buy a gallon of Hydro Pro Si02 coating when I run low on the 22oz bottles.

    All around great product

    I have been using Hydro Blue for a couple of years now and love it. The Hydro Blue Pro kicks it up a notch with longer lasting protection. I use it in my windshield to make the rain run off and almost eliminates the use of wipers. Works especially great in a down pour. Spray it on my wheels to make future cleaning easier. Of course on the paint for great protection and water beading properties. Not only great for vehicles, but I also use it in other applications. For example on my John Deere riding lawn tractor to protect that John Deere green and keep it shining. The product is simple to use and definitely follow directions for the best results. I tell everyone inquiring about taking care of their vehicles about Hydro Blue Pro.

    My go to

    I really like this product. It is easy, quick, and effective


    A must have

    This is by far the easiest to use ceramic there is. It is truly is as easy as spraying on and immediately rinsing off. I use this on my personal vehicles, boat, lawn mowers, wheel barrel. It provides incredible hydrophobic properties. What I really like is that it can be applied to all exterior surfaces, including glass, wheels etc. My wheels stay cleaner longer and are easier to clean when needed. My windshield is like it has had rainX applied. Just make sure you only spray two sprays per panel and immediately rinse it off (pressure washer spreads it much better). If they update the product, I would like to see a bit more gloss if possible. It's glossy but could use more.


    So easy to use with great results

    So easy to apply and the results are great.
