Following corrosion, charges for foils (10)

Ross

I believe the answer is:

frustrates

'foils' is the definition.
('frustrate' can be a synonym of 'foil')

'following corrosion charges' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'corrosion' becomes 'rust' (rust is a kind of corrosion).
'charges' becomes 'rates' (rate is a kind of charge**).
'f'+'rust'+'rates'='FRUSTRATES'

'for' is the link.

I've seen this clue in The Telegraph.
