Gtechniq EXOv5 Coating

• This optional coating forms a durable, long-lasting bond that will not wash off or break down, providing reliable, extended protection for paintwork and other treated surfaces. It creates a strong protective barrier that helps shield against damaging environmental contaminants such as dirt, road grime, and pollutants, while also offering enhanced scratch resistance to maintain a clean, high-gloss finish over time. For those seeking maximum durability and performance, the coating can be applied in multiple layers to increase thickness, strengthen protection, and further extend the life of the surface.
