top advice chaps, Im about to restore an old Claud Butler for a friend and it has an old 3 arm campag sport chromed chainset on it with rust , I'll try the aluminium foil in vinegar.
ah! I found a bike with one of those cranksets, rare as rocking horse poo , polished with alu foil as seen in pic and sold the crank for 100 squid a collector in Taiwan and used the money to pay for the restoration
Here is the before and after on repairing the delivery scratches on the Rossin, not perfect but perfectly OK to get the cosmetics acceptable I r'kn.
Looking forward to see how the Gios shapes up, lovely iconic frame in the right colour
