Hello together, have a new Tiguan and wanted to ask the following question: Below is a picture of a Tiguan rear. Which Pflegmittel is best taken for the chrome parts and which for the black high gloss apron? Or can there be anywhere the Carnauba wax on it? Thanks already. Is a Carnauba wax actually unlimited durable? I bought my 2012 and it is still half full. (in the cool cellar stored)
