Using the Noble Paint - Matched Wing Stabilizer is simple. First, clean the area on your 2015 - 2021 STI wing where you'll attach the stabilizer. Make sure it's dry and free of dirt. Then, peel off the backing of the pre - mounted 3M on the stabilizer and carefully align it with the wing. Press firmly to ensure a good bond. When it comes to maintenance, a regular car wash with mild soap and water is sufficient. Avoid using harsh chemicals or abrasive materials that could damage the paint. If you notice any loose parts, check the 3M adhesive. If it starts to lose its grip, you can replace it with new automotive adhesive. Remember, this stabilizer is designed for your STI wing, so don't try to install it on other vehicles.
