I had my MGB front bumper rechromed in 1991 because the replacements were not the right profile. It cost far more than a new one, and when I asked the bloke at the workshop if there was a guarantee he just laughed.........
It lasted without tarnishing until I sold it in 2008.
Falling over what you put there earlier is a feature of getting older..........
PS....Bath taps never seem to tarnish, but it must be a better quality process.
