Post pictures of your Macan here!
Cheers Marra - yours reminds me of how mine looked before the winter!
One of the things I liked about VG was way the side blades blended in. They were tricky initially as tended to go lighter in areas so I squirt Autoglym Tyre Dressing into a jar and then use a paint brush to lightly paint them when they need it - only twice in 16 months! Works a treat + obviously a good way to treat the tyres & mudflaps as well!
After that, a good pressure wash and drying cloth seems to sort them OK + maybe my mudflaps stop a lot of dirt getting in to them in first place.
Enjoy the motor
