High Performance film is usually a hybrid of dyed construction and metal flake technology. For many years, metallic film was considered a step up from the standard, in both performance and price. The metal flake construction usually has a higher Total Solar Energy Rejection and IR/UV rejection percentage than dyed construction film, and also has a shinier, more metallic appearance than standard dyed construction film. This film can be tricky to use on some newer vehicles because sometimes the metal construction interfere with on-board computer/navigation systems, and other electronic devices. This is a film that sometime comes with a limited lifetime no fade guarantee and is generally considered more fade resistant than standard dyed construction film. Users can usually expect between 5-7 years optimal usage from this film before it might begin to fade.
