[SR-71]

Any surfaces that face forward, or are directly behind the tires catch the most hell but you want to do it right, completely cover it. Expel comes in pre-cut sections, or rolls. Opt for pre-cut. Rolls require the installer use a razer blade to cut the sections to shape and there's a risk the installer could cut into the paint. Also pre-cut sections do not complete cover up under the front and rear bumpers and up under the side. Install additional sections there.

Another plus to covering the car completely is you'll never have waxing swirl marks, and also protection from bird droppings, acid rain, tar, etc. XPEL is simple to keep clean.
