Hello, gave me new A4 a thorough clean yesterday, but found after wash, given its black, that there are hardwater deposits all over it. gave it a good going over with Meguiars NXT Polish, which did help quite alot, but there are still some stubborn markes left if you look closely.
Any suggestions on a surface treatment post wash and pre wax? Or has anyone tried Meguiars NXT car wash which claims to have hardwater combating properties?
Thanks
