I fumbled with a fuel nozzle the other day, and a thimbleful of California's finest premium sloshed over the outside of my 2013 Diavolo Nero GRiSO's fuel tank.
There is some sort of external coating that overlays the silver on this tank. I went to the window wash pot to get a moist rag to wipe it up, and in the ten seconds that took, the fuel had eaten through the external coating on the tank.
WTF. My questions for those more knowledgeable than I.
A.) Who puts a coating on a fuel tank that will not resist fuel, and B.) What Is To Be Done? The finish is eaten through to bare metal in those spots; it's now blotchy, and looks like hell.
