Using these Noble carbon fiber emblems is a breeze. First, make sure the surface where you'll be installing them is clean and dry. You can use a mild soap and water to clean the area on your Subaru WRX or STI. Once it's dry, peel off the backing of the pre - applied 3M on the emblems and carefully place them in the desired location. Press firmly for a few seconds to ensure a good bond. When it comes to maintenance, you can clean them with a soft, damp cloth. Avoid using abrasive cleaners as they might scratch the carbon fiber or the gloss black frame. Also, try to park your car in a shaded area when possible to prevent long - term sun damage. These emblems are built to last, but with proper care, they'll keep looking great for years.
