Sorry but I feel like sounding off!
I don't give a f**k if the bikes been ridden to death in the foulest of weather and kept outside at night - paint shouldn't peel off engine casings or anywhere else in eight months. Somewhere in the law there is something about a product being fit for the purpose it was designed for and as this is a motorcycle that would include riding in bad conditions ( and then parking it up and going to bed as most of us aren't leading a life of complete leisure).
Maybe Ducati ought to make it a condition of sale that you have a centrally-heated garage and swear that you will towel it down if you are stupid enough to get caught in a short shower.
Unless you've been pouring acid over it they should sort it.
I feel better now!
Paul.
