I'm about to get my AMG 7-spoke (black inlay/diamond-cut face) wheels refurbished and am thinking how to preserve the as-new finish for as long as possible. Previously polished/waxed/3 coats of PoorBoys wheel sealant several times a year plus weekly washing, but I am wondering if there are any other options such as the protectant sealants you can now use on paintwork. I want someone hard wearing and my theory is the wheels being as-new will be the perfect time to apply a sealant.
