The front end takes most of the abuse: bumper, hood, fenders, mirrors and headlights. Many customers add rocker panels, door edges and the trunk ledge, or wrap the full car.
Light scratches and swirls in the film disappear with heat. Park in the sun or run warm water over the panel and the surface smooths back out.
Wash it like paint. No wax with abrasives, no pressure washer at the edges. Ceramic coating over the film adds gloss and makes it easier to clean.
