True 'bright & shiny' chrome plate (e.g. automotive trim) is best done by
plating over a proper base. During my summer in the electroplating QC lab for
the major photographic company, the sequence was:
1. copper plate
2. buff to a smooth finish
3. nickel plate
4. repeat step 2
5. chrome plate
Plating onto an ultrasmooth surface was critical, if you didn't 'throw'
chrome onto such a surface, no amount of buffing would make it bright and shiny.
FYI - for the large (36 ton/ 18 ft. diam.) parts, you needed high amperage,
usually between 1500 - 3000 amps. Needless to say, you had to be careful what
you touched in that area!
Following the above sequence gave parts that were mirror bright.
