Using these Noble Red Carbon Fiber Fender Emblems on your 2015 - 2021 Subaru WRX is a breeze. First, clean the area where you'll install the emblems to make sure it's free of dirt and dust. Then, carefully peel off the backing of the 3M adhesive on the emblems. Align the emblem in the desired position on your fender and press it firmly for a few seconds to ensure a good bond. When it comes to maintenance, you can use a mild car cleaner and a soft cloth to gently wipe the emblems. Avoid using abrasive materials that could scratch the carbon fiber finish. Also, be careful when washing your car not to apply too much pressure directly on the emblems. That's all there is to it! Enjoy the stylish new look of your car.
