I apply this product, "Stongard" (same as BMW product) to everyone of my vehicles. Currently on my X5 and E46 ci. I have personally applied this product to over 10 cars. I would not recommend doing the application yourself, without major experience. Also, use "Xpel" for the headlights and fogs for added protection. The only color you will notice the clear protection on, is white. The product tends to yellow a bit on white. Unfortunately both my cars are white, however, I won't be without the protection. You must know it's on the car to even notice it from 5 feet away.
