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.

    A must have

    This stuff really works and is as simple as spray on rinse off and your vehicle is protected. I mainly use it to top ceramic coated vehicle ls but have used as a stand alone

    0ver 3 years and 70k miles and still perfect!

    I purchased my Raptor in December 2018 right after that I used the ceramic SI02 kit from McKees37. Since then I have maintained it with the blue pro SI O2 hydro spray and you will see by the photos it is still like new! What an awesome Product! Getting ready to strip my truck this week and I just purchased the graphene kit to reapply it I am looking so forward to it I’m sure it’s going to be awesome!

    After 3 years and 70k miles!!!!

    When I purchase my Raptor in December of 2018 the first thing I did was ceramic coated with McKees 37 SiO2 series now my Raptor is a little over three years old with 70,000 miles on it and it still looks as good as the day I bought it just using the SIO2 blue pro Hydro spray to maintain the ceramic coating. This we are stripping it and going with the grapheme!!!! I can’t wait!!!!!!

    HBP is a NO BRAINER!!!

    This product is ABSOLUTELY AMAZING! Nick and the team have really hit it out of the park with this one. Impossible to figure out how it works, so stop trying and just use it! Firstly, HBP makes drying the vehicle immensely easier. Once over with a 800GPM microfiber towel and it's done, no more re-wiping. And then there's the SHINE! No other product has made my wife's Orca Black Audi Q8 reflect like a mirror except Hydro Blue. In between washes enjoy the hydrophobic properties - the vehicle feels buttery like a good sealer and even repels nighttime condensation. But it still doesn't end there - because the next time you wash the vehicle, bird droppings and such just rinse right off! HBP is a must for anyone who takes care of their cars, it truly is a no brainer. Not sure yet about the difference between Regular and Pro, perhaps longevity?
