Yes, and bottom of wings can corrode, and around side exhausts, and also rear wheel-arches a bit, and where wings meet front bumper unit, and I believe round front side-lights on some cars. It's all caused by electrolytic reaction and poor consideration of metal to metal interfaces in my view. None of it is serious and is easily repaired. After nearly 8 years since manufacture my Aero looks as good and drives as well as it ever did although I have spent about £1500 - £2000 over the last 4 years on minor repairs due to this corrosion to keep the car looking as near perfect as possible.
Chassis looks absolutely brand new from underneath and looks set to outlive me.
I know that Aston Martins, Ferraris, Lamborghinis and no doubt many other cars using aluminium have similar issues. ACF50 may be a solution but I don't see it stopping electrolytic corrosion.
