Review on 🚗 Winunite 4/5Ft Car Door Edge Guards | No Glue | Black | Universal Fit Rubber | Automotive Door Edge Guard | U Shape | Vehicle Fender Flares | Edge Trim | Car Door Edge Protector | Sedans, Trucks, SUV, ATV, Boat by Ashutosh Takumatla

Easy to use I say start putting it on and use a blunt object to press the panel as close to the door as you can to make it sits snugly (so the doors close), then you can use scissors or a utility knife to trim it. It looks like metal but if you look closely there are small scratches where the metal is in the sections so you can cut the finish. I did all four doors and the back and had enough for another car. Looks natural, does not bulge and does not stick out on the car. Doors close perfectly, tolerates bad weather perfectly.
