Applying these vinyl overlays is a breeze. First, make sure the fender vent area is clean and dry. You can use a mild soap and water to clean it, then dry it thoroughly. Carefully peel the backing off the overlay and align it with the upper or lower fender vent. Slowly press it down, starting from one end and smoothing out any air bubbles as you go. It should take just a few minutes. When it comes to maintenance, avoid using abrasive cleaners. A soft cloth and a gentle car - cleaning solution will do the trick. And try to park your car in the shade as much as possible to prevent the sun from causing the overlays to fade over time. That's all you need to know to keep your car looking great with these overlays!
