I read a thing... Water displacement. Immediately I am thinking that this can not only be used on engine bay plastics, but just spray and allow to dry. Wherever. Koch Chemie highlights the specific words 'power units' 'engines' 'housing parts'. Spray onto clean surfaces, close the hood, walk away.
Koch Chemie Motorplast Engine Bay Dressing 500ml dries completely and prevents dirt from sticking to your surfaces. It also protects metal parts from corrosion with a protective film.
Includes spray head
