I've searched for this on here but only found the issue over on cutters. Have any CSL owners had this corrosion? I found someone had quoted a pair of the mirror pillars at BMW were £530ish unpainted. I only need one, if BMW won't repair it, so I'm wondering do I buy a single one or can it be repaired? I guess this would involve removing it, sand blasting it then re-prepping and painting etc. If you have any experience of this I'd be interested to know.
Thanks
