A multilayer thermoformable film to protect the surface of a workpiece includes an underlayer having first and second faces. The underlayer is made from an adhesive material configured to adhere to the surface of the workpiece by the first face. At least one layer of polymer material is attached to the second face of the adhesive underlayer. The layer of polymer material is resistant to erosion by solid particles and to erosion by liquid particles. It is formed from a polymer material chosen from a polyurethane, a polyether ether ketone and a polyethylene having a very high molecular weight, with a Shore D hardness of between 50 and 65 D. A method of surface protection of the workpiece includes thermoforming the film in a shape adapted to match the shape of at least a portion of the workpiece and applying the film thermoformed onto the surface of the workpiece.
