Hi Absolutanne,
I am afraid you and all others that have the misfortune to buy Gucci leathers are going to experience these problems.
I know because I just talked to a Gucci Group Customer Care person and he said all Gucci leather is UNCOATED. This means that it will stain and age quickly no matter what. It does not say it anywhere on the sewn in or attached labels, so I guess we have to learn by our mistake in trustig a leading design company like Gucci. Of course when you buy the product, you may spray it or have it processed at your own expense, but Gucci takes no responsibility for it.
I work for a man who just bought a gorgeous $3000 brown leather jacket, wore it 2 days and accidently got caught in the rain. He took it back because it was stained by the rain, was given a difficult time because the salesperson said it was uncoated leather and my boss should have known that would happen. He asked me to call Gucci for him and put in a complaint for him which I did and is in progress.
I really suggest that all of you with similar experiences out there write to the Gucci Group (73 Via Tornabuoni 50100, Florence, Italy) and put in your complaints. Take pictures and show them their product is only good for the showroom windows and not for real use and maybe it will get their attention that something needs to be done to protect their sales as well as their leathers.
If we all do our part maybe we can have the quality back in the Gucci prodcuts we all know and love.
Good Luck
