hmm .. that sounds like a good idea castle king.
But it does sound like this rusting issue really is a common problem .. and it DOES look unsightly.
Why on earth are BMW allowing this to happen.
If i experience this problem, I will be asking the dealer to resolve the problem 1st.
Failing that, I may have to try the wire-brush or hammerite treatment ... but why should we have to do this to our brand new cars if its an established fault ... why aren't BMW painting the affected areas ?
Yo NFS, we'll have to monitor our wheels for this issue, when we get our motts next month ... you'll have a week's head start on me so keep us posted
