i'd just watch it, see if it spreads and how quickly... if it does start to spread, you might want to contact the manfer and see if they want it back.
also... i've had, in my life, carbon deposits that looked, to me, like wear through the chrome, but later turned out to just be, as i said, weird carbon deposits. are you SURE thats not what it is?
