Can not fault this seal. It does what it should do. It's kind of like the clear coat is sprayed on. You should definitely visit a garage before you start, or there must be no wind. Because otherwise it may happen that the paint is fogged on the car itself or the windshield. Depending on how you work. Did the whole engine sprayed with it. Super result. IMPORTANT: before cleaning the engine and possibly even black plastic on the plastic parts to apply the color refresh and seal them with the remaining parts. Then looks like on my picture here (Audi 4.2L engine)
