Oh yes definitely worth it. A good coating will not only stone chip proof your car but also deflect .22 bullet at 45 degrees fired at 3 meters away without any dent and scratches making your paint virtually vandal proof. However you can expect minor coating chip with .25 onwards bullet but nothing irreparable with 5mins touch up at the coating dealer. The coating is also electro chemically charged with magnetic ion at factory, creating a 0.05mm repellant field above the coating for dust and dirt to rest on so when your car moves above the speed of 25kmh any dust, dirt, water mark will glide away against the wind force. Waxing will void the coating warranty.
