Using these fender vent vinyl overlays is easy. First, clean the area where you'll be applying them to make sure it's free of dirt and dust. Then, carefully peel off the backing and stick the vinyl overlay onto the fender vent, smoothing out any air bubbles as you go. When it comes to maintenance, just use a mild soap and water to clean them. Avoid using abrasive materials that could scratch the vinyl. Also, try to park your car in the shade as much as possible to prevent the vinyl from fading due to long - term sun exposure. With proper care, these overlays will keep your car looking great for a long time.
