Hi, thanks for the input about the badge. I think I will get all the blue out and leave it. You are so right about the mirrors. My plus four is Sept 2011 and I was adjusting the mirrors so I might see something behind the car ( anything rather that sky) and noticed the corrosion on the chrome. I think I am going to have to keep well on top of the cleaning. Can't wait for the salt to be off the roads so I can get the car out.
