Solvol Autosol is what I always used for detailing my bikes shiny bits, it's a very fine cutting paste available in most car accessory shops, about a fiver for a tube... perhaps the wet and dry as mentioned ...then the solvol to fine finish
Personally I would use Scotchbrite (or the cheaper Mirka version if I'm being honest ) for a nice brushed finish, the ultra fine ones have a decent sheen in my opinion.
