Mr Sheen is always a good one to be honest, but I use Maguire's (sp???) gold glass I think it's called and their scratch-x stuff for obvious light scratches.
It's a car polish but it really brings up a deep gloss finish, great one black etc, always use a lint free polishing cloth too so non of those swirls etc
Wheels I use WD40 to get the grease and grime off, and they usually come up a treat there, but if I am feeling attentive I'll probably go with some purple helmet or autoglym aerosol polish also (smells of apples
)
