lovely job! I have just spent 12 hours cleaning my M3 convertible. this almost puts my effort to shame! having t-cut and polished when bought, i have just discovered clay and used Autoglym's version to do the whole car yesterday... what a great result it gives... provides a super-smooth finish to apply a new coat of resin polish. Also used Renovo soft-top refurbishing products (about £70 for cleaner/renovator/sealer) on advice of a friend... highly recommended, roof looks like new.
what did you use on the exhaust? mine is filthy and considering duraglit, but not sure if that is too harsh. also, did you pressure wash the engine? again mine is dirty but save for a damp cloth wipe, I am reluctant to shower it in water... thoughts?
nice job, thanks for the pictures. I'm off to Autoglym cream the seats now :o)
