Using this Noble Essentials STI Rear Trunk Emblem is super easy. First, clean the area on your Subaru's rear trunk where you want to install the emblem. Make sure it's dry and free of dust. Then, peel off the backing of the emblem and carefully stick it in place. Press firmly for a few seconds to ensure it adheres well. Since this is a clearance item with a top - coat defect, be a bit more careful when handling it. Avoid scratching the top - coat further. For maintenance, you can clean it with a mild car cleaner and a soft cloth. Just wipe gently to keep it looking good. Remember, this item can't be returned, so make sure it's what you want before installing.
