The stone guard film extends the life of your vehicle by protecting it from numerous external assaults such as sand, rocks or the various abrasives spread on the roads.

Always applied with meticulous care, the film, composed mainly of thermoplastic urethane, is covered with the same varnish as the one found on vehicles, thus ensuring a uniform and aesthetic finish at all times. Similar to paint, this protective layer also prevents the various solvents and chemical products from penetrating the original paint components and cause damage and discolouration.

Lettra's experts install the stone barrier and apply this thin film, which is entirely laser-cut for greater precision and an optimal and impeccable final result.
