NANOSKIN HYDRO EXPRESS is technically a spray polymer sealant. Through the use of advanced hydrophobic polymer formula, NANOSKIN has created a spray polymer that actually repels water, dissipates static, and adds additional protection to your finish. HYDRO EXPRESS can also be used on glass, chrome, and plastic. The spray dries crystal clear on any surface and enhances reflections on shiny materials, like chrome wheels and trim. It’s so easy and you can detail and protect a full size car in less than 10 minutes.
