Final Coat α has undergone a change in model. This simple water-repellent glass coating can remove water deposits and dirt from glass surfaces while coating them, all in one step. The original’s excellent ease-of-use has been improved even further. By revising the concentrations of silicone and fluorine, wait time after application has been reduced and it is easier to wipe off, allowing for a cleaner finish. It is as durable as ever, lasting 3-6 months.
