Although silica-based coatings offer outstanding protection against the elements, they still need to be maintained for best results. Nanolex Final Finish is perfect for this task, as it quickly and efficiently lays down a fresh layer of ultra-smooth, fully synthetic, nano-scale protection that has a life expectancy of up to four weeks per application. That's impressive for a quick detailer, but in all honesty we'd expect nothing less from Nanolex!
