Using this Noble paint - matched wing stabilizer is a breeze. First, find a clean and dry surface on your 15 - 21 STI wing. Then, take the stabilizer and peel off the backing of the pre - mounted 3M on the top and bottom edges. Carefully align it with the wing and press it firmly to secure it in place. When handling the stabilizer, be gentle to avoid scratching the paint. For maintenance, you can use a mild car cleaner and a soft cloth to clean it regularly. This will help keep its finish looking great and ensure it lasts a long time. Also, avoid using harsh chemicals as they might damage the paint or the 3M adhesive.
