Since I have received a lot of help from you, I would also like to give you a tip, of course unpaid and from the whole heart. The Koch Chemie Motorplast, is in addition to the engine seal, where there are enough reviews, especially suitable for the following external areas: – painted- (no high gloss/piano lacquer) or unpainted plastic e.g. grill, fan intakes etc. – black-laced metal – cromized plastic With black, there is a very nice color refresher, more than e.g. .: Sonax Brilliant Shine Detailer, with which I also had on scrammed plastic, not such a gloss. Of course it is water repellent and has a longer service life, although I can not say anything about it. One can also use it for the tire care, if someone has intresse, I like to test it. It is very light, and fast to apply, either with a micro-carrier cloth or directly from the bottle, let dry about 12 hours and give fals remove the surpluses. At the beginning you don’t see the colour refresher yet so clearly, because it really takes time to dry, so please don’t apply too much here. The picture is from our well-known car and you can see the difference.
