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.

    Amazing Product

    Some time back a friend gave me a spray bottle of this product. I read the instructions and thought this can't possibly work. I have a dark blue 2018 Charger SRT. I've kept it pretty darn clean and polished so what can this spray possibly do for me? Then I tried it. Absolutely unbelievable the sheen this product left on the paint. And it's a very durable sheen. Very impressive. So I've continued to use it maybe every fifth wash, and the car continues to look as if it just came off the showroom floor. Plus it is so easy to apply. No elbow grease required. I have now seen similarly named products on parts store shelves, but I'm staying with your product because it works so fantastically well.
