Beautiful work! I just bought a 2015 Merc. E Class with that paint color and condition nearly as bad. I'd love to know your pad/product combination as I'm finding the paint very difficult to correct. Best I've found so far is Fast Correcting Cream with a Boss MF pad but even that combo is requiring a fair amount of time to correct. I am working with a GG6 so clearly not the same level of power as a Flex or a long throw, though.
