To my delight and surprise (remember, NONE of the alloy on Harleys is andodised/coated - ie it's good old polishable, bare metal) there was virtually no corrosion on the bike at all, anywhere, and this is after it sitting in the garage, covered in salty grime, for over 3 weeks.
ACF isn't cheap - a litre bottle will cost itro 25-30 quid - but it certainly works. Best way to apply it is with a paintbrush (it's a gloopy-ish consistency) or moisten a rag with it and wipe on.
Good stuff it is
