3M is right. It is often referred to as Rock or Stone Guard. The product comes in various lengths and thickness depending on the application and can be applied to hood, bumper, fenders, foglights, side mirrors etc.
Both of my vehicles are protected. Way better than car bras/masks, those things scratch your paint and look hideous. The 3M will protect and keep a nice clean look. I highly recommend you call a tint shop, they will likely be able to help you out. About $75.00 Cdn for my SVT (12" of hood and arched the front fenders around the headlights).
