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. The PRO version has 50% more SiO2 compared to the standard Hydro Blue!
