McKee's 37 Hydro Blue SiO2 Coating - 16 oz.

Hydro Blue works best on a vehicle that is well maintained meaning it was recently clayed and polished. The smoother the surface the longer the hydro Blue will last. Working ONE panel at a time on a vehicle that was just washed and rinsed but not dried. Spray Hydro Blue directly onto the panel and immediately rinse off using a strong jet of water. Then dry the vehicle using McKee’s 37 Turbo Dryer or a microfiber drying towel.
