Using the Noble Essentials STI Rear Trunk Emblem is super easy. First, clean the area on the rear trunk where you want to install the emblem to make sure it's free of dirt and grease. Then, peel off the backing of the emblem and carefully stick it in place. Press firmly for a few seconds to ensure a good bond. Remember, this is a clearance item with a defect in the top - coat, so don't expect it to be perfect. Also, since it's a clearance item, it can't be returned. For maintenance, simply wash it gently with mild soap and water when your car gets dirty. Avoid using abrasive cleaners as they might damage the emblem's surface.
