Nanolex Ultra Glass Sealant is a state of the art nanotechnology coating that lays down a film of nano-scale silica components and functional additives that hardens to form a fully transparent hydrophobic barrier layer that repels rain, sleet and snow upon contact. The coating works in conjunction with airflow over the car to rapidly disperse water droplets at speeds above 30 mph, resulting in vastly improved visibility and driving comfort, even under extreme weather conditions. Indeed, independent academic studies have shown that similar treatments allow drivers to recognise objects up to one second earlier in wet weather conditions. At 60 mph, this one second advantage can reduce stopping distances by up to 30 m, thus improving safety for everyone on the road. Providing that the treated surfaces are properly prepared in advance, each application of Nanolex Ultra Glass Sealant will last for between eighteen months to two years before needing to be reapplied. We have used Nanolex Ultra Glass Sealant on a number of our daily drivers over the years, and it works exceptionally well, particularly if you do a lot of high speed driving.
