Gtechniq HALO Flexible Film Coating Protection for PPF and Vinyl Wrap - (30ml) HALO enhances the performance of Paint Protection Film (PPF) and vinyl. It’s a chemically bonding, ultra-dense flexible film that becomes the permanent surface of the film – protecting it from the elements a car faces on a daily basis. The density of the coating and its low surface energy improve dirt and water repellency of PPF or vinyl. It also helps to prevent staining from dirt ingression, as well as reducing yellowing caused by UV rays.
