Why Use Gtechniq EXO? EXOv4 delivers a hard film that makes water-spots easy to remove, offers great resistance to all wash chemicals and can help withstand micro-marring. It produces a high-gloss, warm-looking, extreme hydrophobic finish. It has a consistent film that is more durable and resistant to road salt and washes chemicals than its predecessors. Application is easy, with a slow flash-off time, giving more time to achieve a perfect finish. All of the above combined with the introduction of a good degree of swirl resistance means EXOv4 represents a major leap forward in Last Surface Protection (LSP) technology.
