These pinstripes are custom cut to fit the 2015-2018 rear bumper. Beware of other sellers selling strips of vinyl that are not contoured to fit the bumper properly.
This material is durable and will last for years.
Clean the surface of the bumper. The easiest way to apply this is to wet the back of the vinyl. You can even use a little soap. This will allow you to slide the vinyl around, but will make it harder to stick. You will have to wait until it dries completely to complete a wet installation. Start at one corner and slowly apply the stripe to the bumper. Continue until you reach the other corner.
