Amazing...I'm particularly interested in how to maintain those AMG 3 piece wheels as I've found that they are very high maintenence indeed.
I am actually finding I avoid using the SEC now for the thoughts of skinned fingers and autosol after any journey in even the slightest of damp conditions.
I think im just going to have to stop being so particular, live with the water marks and just let them get used...
The poorboys wheel sealant does help though.
