Hi,
I just noticed a tiny rust spot on the doorsill while washing my 1-month old Rogue last week. It was a minuscle piece of metal trapped by the weatherstripping rubber that started the corrosion. It is so tiny that I'm afraid the dealer will laugh at my face if I show it to him, but it is definetely there and will get worse if I don't do anything about it. What should I do? Is there any recommended product to prevent the corrosion to advance any further or is it too late?
