Using these emblems is a breeze. First, clean the area where you want to install the emblems thoroughly to ensure a good bond. Then, peel off the backing of the pre - applied 3M on the emblems and carefully place them in the right position on your Subaru WRX or STI. Press firmly to make sure they stick well. When it comes to maintenance, just use a mild car cleaner and a soft cloth to wipe them down. Avoid using abrasive materials as they might scratch the carbon fiber or the gloss black frame. Also, be careful when washing your car not to apply too much pressure directly on the emblems. That's all you need to know to keep your new emblems looking great for a long time.
