Denim Black Oxidation

[Mikefbald1]

Got a 2015 Denim Black SGS with serious signs of what appears to be oxidation on both fenders, tank, and cargo lids. Dealership no help. Anybody have similar issue?

I've got a 2015 demin black SGS as well and it does not have any signs of that. I would be interested to see any pics and find out what you have used to wash and maintain the bike. Does it sit outside or is it garaged?
